Python program removes punctuation from the string

Complete Python Examples

This program removes all punctuation marks from the string. We will use a for loop to check each character of the string. If the character is a punctuation mark, we assign an empty string to it.

To understand this example, you should understand the followingPython programmingTopic：

• Python for loop

• Python string

• Python if ... else statement

Sometimes, we may want to split a sentence into a list of words.

In this case, we may first need to clean the string and remove all punctuation marks. Below is an example of how to complete this function.

Source code

#　Define punctuation marks
punctuations　=　'''!()-[]{};:'"\,<>./?@#$%^&*_~'''
my_str　=　"Hello!!!,　he　said　---and　went.
#　Accept user input
#　my_str　=　input("Enter a string:　")
#　Remove punctuation from the string
no_punct　=　""
for　char　in　my_str:
　　　if　char　not　in　punctuations:
　　　　　　　no_punct　=　no_punct　+　char
#　Display the string without punctuation
print(no_punct)

Output result

Hello　he　said　and　went

In this program, we first define a string of punctuation marks. Then, we use a for loop to iterate over the provided string.

In each iteration, we check if the character is a punctuation mark or if it uses a membership test. We have an empty string, and if it is not a punctuation mark, we add (connect) the character to it. Finally, we display the cleaned string.
