9 Handy Python Functions for Programmers

Based on my personal scripting experience .9 Handy Python Functions for Programmers

Python is very handy in terms of shortcuts this language provides. Some of the shortcuts are very useful, make the scripting much faster, and optimizing your code.

These shortcuts are available in the Python libraries, and using them can make your code work faster and more easily. We need to become used to these functions so that we can utilize them when needed and save our time.

In this article, I will share the nine most useful functions I have come up with based on my personal coding experience.

1. reversed()

While programming, we often need to reverse a string or a list. For reversing any object, Python provides a function that can be utilized to optimize your code, instead of using a loop to make it reversed.

# Reversed for string
seq_string = 'Python'
print(list(reversed(seq_string)))

# Reversed for tuple
seq_tuple = ('P', 'y', 't', 'h', 'o', 'n')
print(list(reversed(seq_tuple)))

# Reversed for range
seq_range = range(5, 9)
print(list(reversed(seq_range)))

# Reversed for list
seq_list = [1, 2, 4, 3, 5]
print(list(reversed(seq_list)))
Output
['n', 'o', 'h', 't', 'y', 'P']
['n', 'o', 'h', 't', 'y', 'P']
[8, 7, 6, 5]
[5, 3, 4, 2, 1]

In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
