PySpark Cheat Sheet: Spark DataFrames in Python

This PySpark SQL cheat sheet is your handy companion to Apache Spark DataFrames in Python and includes code samples.

You'll probably already know about Apache Spark, the fast, general and open-source engine for big data processing; It has built-in modules for streaming, SQL, machine learning and graph processing. Spark allows you to speed analytic applications up to 100 times faster compared to other technologies on the market today. Interfacing Spark with Python is easy with PySpark: this Spark Python API exposes the Spark programming model to Python. 

Now, it's time to tackle the Spark SQL module, which is meant for structured data processing, and the DataFrame API, which is not only available in Python, but also in Scala, Java, and R.

Without further ado, here's the cheat sheet:

This PySpark SQL cheat sheet covers the basics of working with the Apache Spark DataFrames in Python: from initializing the SparkSession to creating DataFrames, inspecting the data, handling duplicate values, querying, adding, updating or removing columns, grouping, filtering or sorting data. You'll also see that this cheat sheet also on how to run SQL Queries programmatically, how to save your data to parquet and JSON files, and how to stop your SparkSession.

Spark SGlL is Apache Spark's module for working with structured data.

Initializing SparkSession 
 

A SparkSession can be used create DataFrame, register DataFrame as tables, execute SGL over tables, cache tables, and read parquet files.

>>> from pyspark.sql import SparkSession
>>> spark a SparkSession \
     .builder\
     .appName("Python Spark SQL basic example") \
     .config("spark.some.config.option", "some-value") \
     .getOrCreate()

Creating DataFrames
 

Fromm RDDs

>>> from pyspark.sql.types import*

Infer Schema

>>> sc = spark.sparkContext
>>> lines = sc.textFile(''people.txt'')
>>> parts = lines.map(lambda l: l.split(","))
>>> people = parts.map(lambda p: Row(nameap[0],ageaint(p[l])))
>>> peopledf = spark.createDataFrame(people)

Specify Schema

>>> people = parts.map(lambda p: Row(name=p[0],
               age=int(p[1].strip())))
>>>  schemaString = "name age"
>>> fields = [StructField(field_name, StringType(), True) for field_name in schemaString.split()]
>>> schema = StructType(fields)
>>> spark.createDataFrame(people, schema).show()

 

From Spark Data Sources
JSON

>>>  df = spark.read.json("customer.json")
>>> df.show()

>>>  df2 = spark.read.load("people.json", format="json")

Parquet files

>>> df3 = spark.read.load("users.parquet")

TXT files

>>> df4 = spark.read.text("people.txt")

Filter 

#Filter entries of age, only keep those records of which the values are >24
>>> df.filter(df["age"]>24).show()

Duplicate Values 

>>> df = df.dropDuplicates()

Queries 
 

>>> from pyspark.sql import functions as F

Select

>>> df.select("firstName").show() #Show all entries in firstName column
>>> df.select("firstName","lastName") \
      .show()
>>> df.select("firstName", #Show all entries in firstName, age and type
              "age",
              explode("phoneNumber") \
              .alias("contactInfo")) \
      .select("contactInfo.type",
              "firstName",
              "age") \
      .show()
>>> df.select(df["firstName"],df["age"]+ 1) #Show all entries in firstName and age, .show() add 1 to the entries of age
>>> df.select(df['age'] > 24).show() #Show all entries where age >24

When

>>> df.select("firstName", #Show firstName and 0 or 1 depending on age >30
               F.when(df.age > 30, 1) \
              .otherwise(0)) \
      .show()
>>> df[df.firstName.isin("Jane","Boris")] #Show firstName if in the given options
.collect()

Like 

>>> df.select("firstName", #Show firstName, and lastName is TRUE if lastName is like Smith
              df.lastName.like("Smith")) \
     .show()

Startswith - Endswith 

>>> df.select("firstName", #Show firstName, and TRUE if lastName starts with Sm
              df.lastName \
                .startswith("Sm")) \
      .show()
>>> df.select(df.lastName.endswith("th"))\ #Show last names ending in th
      .show()

Substring 

>>> df.select(df.firstName.substr(1, 3) \ #Return substrings of firstName
                          .alias("name")) \
        .collect()

Between 

>>> df.select(df.age.between(22, 24)) \ #Show age: values are TRUE if between 22 and 24
          .show()

Add, Update & Remove Columns 

Adding Columns

 >>> df = df.withColumn('city',df.address.city) \
            .withColumn('postalCode',df.address.postalCode) \
            .withColumn('state',df.address.state) \
            .withColumn('streetAddress',df.address.streetAddress) \
            .withColumn('telePhoneNumber', explode(df.phoneNumber.number)) \
            .withColumn('telePhoneType', explode(df.phoneNumber.type)) 

Updating Columns

>>> df = df.withColumnRenamed('telePhoneNumber', 'phoneNumber')

Removing Columns

  >>> df = df.drop("address", "phoneNumber")
 >>> df = df.drop(df.address).drop(df.phoneNumber)
 

Missing & Replacing Values 
 

>>> df.na.fill(50).show() #Replace null values
 >>> df.na.drop().show() #Return new df omitting rows with null values
 >>> df.na \ #Return new df replacing one value with another
       .replace(10, 20) \
       .show()

GroupBy 

>>> df.groupBy("age")\ #Group by age, count the members in the groups
      .count() \
      .show()

Sort 
 

>>> peopledf.sort(peopledf.age.desc()).collect()
>>> df.sort("age", ascending=False).collect()
>>> df.orderBy(["age","city"],ascending=[0,1])\
     .collect()

Repartitioning 

>>> df.repartition(10)\ #df with 10 partitions
      .rdd \
      .getNumPartitions()
>>> df.coalesce(1).rdd.getNumPartitions() #df with 1 partition

Running Queries Programmatically 
 

Registering DataFrames as Views

>>> peopledf.createGlobalTempView("people")
>>> df.createTempView("customer")
>>> df.createOrReplaceTempView("customer")

Query Views

>>> df5 = spark.sql("SELECT * FROM customer").show()
>>> peopledf2 = spark.sql("SELECT * FROM global_temp.people")\
               .show()

Inspect Data 
 

>>> df.dtypes #Return df column names and data types
>>> df.show() #Display the content of df
>>> df.head() #Return first n rows
>>> df.first() #Return first row
>>> df.take(2) #Return the first n rows >>> df.schema Return the schema of df
>>> df.describe().show() #Compute summary statistics >>> df.columns Return the columns of df
>>> df.count() #Count the number of rows in df
>>> df.distinct().count() #Count the number of distinct rows in df
>>> df.printSchema() #Print the schema of df
>>> df.explain() #Print the (logical and physical) plans

Output

Data Structures 
 

 >>> rdd1 = df.rdd #Convert df into an RDD
 >>> df.toJSON().first() #Convert df into a RDD of string
 >>> df.toPandas() #Return the contents of df as Pandas DataFrame

Write & Save to Files

PythonPillowを使用して画像を処理および操作する方法

この記事では、PythonPillowまたはPILライブラリを使用して画像を処理および操作する方法を学習します。

PillowとPIL（Python Imaging Library）は同じです。PILはPython2で使用されました。Pillowは、現在Python3と互換性のあるPILリポジトリのフォークです。このライブラリは、主に画像の開き、処理、変換に使用されます。Windows、Mac OS X、Linuxで利用できます。このライブラリを使用すると、サイズ変更、トリミング、ファイル変換、回転など、いくつかの画像操作を実行することもできます。

枕の設置

PillowをWindowsにインストールするには、ターミナルウィンドウを開き、次のコマンドを実行します-

pip install pillow

このライブラリは私の作業システムにプリインストールされているので、次のようになります-

Requirement already satisfied: pillow in c:\python37\scripts\projects\env\lib\site-packages (7.0.0)

インストールを確認してください

インストールされているバージョンを印刷することで、Pillowが正常にインストールされたことを確認できます。

import PIL
print('Pillow Version:', PIL.__version__)

(env) c:\python37\Scripts\projects>pillow1.py
Pillow Version: 7.0.0

ピロー：画像を読み込む

それでは、Pillowライブラリを使用して画像を開く方法を見てみましょう。画像処理の最も一般的なモジュールは画像モジュールです。ここでは、このモジュールのopen（）メソッドを使用して画像を読み取りました。

from PIL import Image
img = Image.open('beautifultree.jpg')
img.show()

枕：色変換

Python Pillowは、色変換用のconvert（）メソッドを提供します。次のコードは画像を読み取り、グレースケールに変換します。また、save（）メソッドを使用して生成されたグレースケール画像を保存しました。

from PIL import Image
img = Image.open('beautifultree.jpg')
img_cov = img.convert('L')
#show image
img_cov.show()
#save image
img_cov.save("bt_gray.jpg")

枕：画像のトリミング

image.crop（）は、画像をトリミングするために使用されます。4つのタプル（左、上、右、下）で定義された画像から領域をトリミングします。

枕：回転画像

画像を回転するには、Image.rotate（）メソッドを使用します。回転角を属性として取り、画像の回転コピーを返します。

from PIL import Image
img = Image.open('beautifultree.jpg')
cropped = img.rotate(180)
#show image
cropped.show()

ピロー：サムネイルを作成する

枕を使用してサムネイルを作成するのは非常に簡単です。サムネイルサイズを指定するタプルを取得し、画像をサムネイルに変換するthumbnail（）メソッドを提供します。

 

枕：形を描く

枕モジュールを使用すると、長方形、多角形、楕円などのさまざまな形状を描画することもできます。与えられた例では、ImageDrawモジュールを使用して2つの長方形、1つのポリゴンと1つの楕円を描画しました。このモジュールは、画像オブジェクトのシンプルな2Dグラフィックスを提供します。

from PIL import Image, ImageDraw

img = Image.new('RGBA', (200, 200), 'yellow')    
idraw = ImageDraw.Draw(img)
idraw.rectangle((10, 10, 100, 100), fill='blue')
idraw.rectangle((100, 100, 250, 200), fill='cyan')

idraw.polygon([(200,10), (200, 200), (150,50)], fill = 'red')
idraw.ellipse((20, 20, 90, 90), fill = 'green', outline ='black')
img.show()
