Python program to remove punctuation from the string

Python Example大全

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

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

• Python for loop

• Python strings

• 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. Below is an example of how to accomplish this function.

Source code

# Define punctuation
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. Then, we use a for loop to iterate over the provided string.

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