How to perform string operations on every element of a list of strings

Question

I have a list of strings. I want to perform some operations on every element of the string. How to do it?

Answer 1

This can be done using list comprehension in Python. List comprehension is an elegant way to define and create list in python. We can create lists just like mathematical statements and in one line only. The syntax of list comprehension is easier to grasp. For example,

# below list contains square of all odd numbers from
# range 1 to 10
odd_square = [x ** 2 for x in range(1, 11) if x % 2 == 1]
print(odd_square) # This will print [1,9,25,49,81]
