String methods in Python

String methods:

  • str.capitalize(): Returns copy of the string with its first character capitalized and rest of the letters in lowercase.
#capitalize-Only first character of string is capitalized
	s1="example of string methods"
	print (s1.capitalize()) #Output:Example of string methods
	s2="EXAMPLE OF STRING METHODS"
	print (s2.capitalize())#Output:Example of string methods
  • str.title()- Returns copy of string where first character in every word is upper case.
s1="example of strings"
	print (s1.title()) #Output:Example Of Strings
  • str.casefold(): Returns casefolded copy of the string. Converts string to lower case. Casefolding is similar to lowercasing but more aggressive because it is intended to remove all case distinctions in a string.
#casefold- converts all character to lower case
	s1="Example Of String Methods"
	print (s1.casefold()) #Output:example of string methods

	s2="ß-Beta"
	#ß-lowercase is equivalent to ss. casefold converts it to ss. But lower doesn't do that.
	print (s2.casefold()) #Output: ss-beta
	print (s2.lower())#Output: ß-beta
  • str.swapcase():Returns copy of string with uppercase characters converted to lowercase and vice versa.
s1="example of strings"
	print (s1.swapcase()) #Output:EXAMPLE OF STRINGS

	s2="EXAMPLE OF STRINGS"
	print (s2.swapcase()) #Output:example of strings

	s3="Example Of Strings"
	print (s3.swapcase()) #Output:eXAMPLE oF sTRINGS
  • str.lower()-Returns copy of string in lowercase.Symbols and numbers are ignored.
s1="Example Of Strings"
	print (s1.lower()) #Output:example of strings

	s2="EXAMPLE OF STRINGS??"
	print (s2.lower())#Output:example of strings??

	s3="1.example of strings?"
	print (s3.lower()) #Output:1.example of strings?
  • str.upper()-Returns copy of string in uppercase.Symbols and numbers are ignored.
s1="Example Of Strings"
	print (s1.upper())#Output:EXAMPLE OF STRINGS

	s2="EXAMPLE OF STRINGS??"
	print (s2.upper())#Output:EXAMPLE OF STRINGS??

	s3="1.example of strings?"
	print (s3.upper()) #Output:1.EXAMPLE OF STRINGS?
  • str.encode():Returns an encoded version of the string in byte format.
str.encode(encoding=”encoding”,errors=”errors”)

encoding(Optional):Default encoding is “utf-8”

errors(Optional):Default errors is “strict”.Raise unicode error.

s1= "example öf strings"
	print (s1) #Output:example öf strings

	#Use backslash for the character that can't be encoded
	print(s1.encode(encoding="ascii",errors="backslashreplace")) #Output:b'example \\xf6f strings'

	#ignores the character that can't be encoded
	print(s1.encode(encoding="ascii",errors="ignore"))#Output:b'example f strings'

	#replace the character that can't be encoded with the text explanining the character. 
	print(s1.encode(encoding="ascii",errors="namereplace"))#Output:b'example \\N{LATIN SMALL LETTER O WITH DIAERESIS}f strings'

	#Replace the character that can't be encoded with the question mark
	print(s1.encode(encoding="ascii",errors="replace"))#Output:b'example ?f strings'

	#Replace the character that can't be encoded with xml character.
	print(s1.encode(encoding="ascii",errors="xmlcharrefreplace"))#Output:b'example öf strings'

	#strict-Raise Unicode Error
	print(s1.encode(encoding="ascii",errors="strict"))
	#Output:UnicodeEncodeError: 'ascii' codec can't encode character '\xf6' in position 8: ordinal not in range(128)

	#errors are not mentioned.Default is strict-Raise Unicode Error.
	print(s1.encode(encoding="ascii"))
	#Output:UnicodeEncodeError: 'ascii' codec can't encode character '\xf6' in position 8: ordinal not in range(128)
  • str.startswith()- Returns True, if the string starts with specified value, otherwise returns False.

How To Compare Tesla and Ford Company By Using Magic Methods in Python

Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc…

You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like init, call, str etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).

Now there are a number of such special methods, which you might have come across too, in Python. We will just be taking an example of a few of them to understand how they work and how we can use them.

1. init

class AnyClass:
    def __init__():
        print("Init called on its own")
obj = AnyClass()

The first example is _init, _and as the name suggests, it is used for initializing objects. Init method is called on its own, ie. whenever an object is created for the class, the init method is called on its own.

The output of the above code will be given below. Note how we did not call the init method and it got invoked as we created an object for class AnyClass.

Init called on its own

2. add

Let’s move to some other example, add gives us the ability to access the built in syntax feature of the character +. Let’s see how,

class AnyClass:
    def __init__(self, var):
        self.some_var = var
    def __add__(self, other_obj):
        print("Calling the add method")
        return self.some_var + other_obj.some_var
obj1 = AnyClass(5)
obj2 = AnyClass(6)
obj1 + obj2
