remove r and n from string python

Removing 'r' and 'n' from a string in Python

To remove the characters 'r' and 'n' from a string in Python, you can use the replace() method. Here are the steps to do it:

1. Define the string you want to modify.
2. Use the replace() method to replace the characters 'r' and 'n' with an empty string.

Here's an example code snippet that demonstrates this process:

string = "Hello, world!"
modified_string = string.replace('r', '').replace('n', '')
print(modified_string)

Output:

Hello, wold!

Explanation of the steps: 1. We define a string variable string with the value "Hello, world!". 2. We use the replace() method twice to remove the characters 'r' and 'n' from the string. The first replace() call replaces 'r' with an empty string, and the second replace() call replaces 'n' with an empty string. 3. We assign the modified string to a new variable modified_string. 4. We print the modified_string, which is the original string with 'r' and 'n' removed.

Please note that the replace() method replaces all occurrences of the specified characters in the string. If you only want to remove the first occurrence, you can use the replace() method with the count parameter set to 1, like this: string.replace('r', '', 1).
