remove a substring from a string in python

To remove a substring from a string in Python, you can use the replace() method of the string object. Here is an example:

main.py
original_string = "Hello, World!"
substring_to_remove = ", "
new_string = original_string.replace(substring_to_remove, "")
print(new_string)
141 chars
5 lines

In this example, we first define an original string "Hello, World!" and a substring to remove ", ", which is a comma and a space. We then use the replace() method to create a new string without the substring. The resulting string is "HelloWorld!", as the ", " substring has been removed.

Alternatively, you can also use string slicing to remove a portion of a string. Here is another example:

main.py
original_string = "Hello, World!"
substring_to_remove = ", "
start_index = original_string.find(substring_to_remove)
end_index = start_index + len(substring_to_remove)
new_string = original_string[:start_index] + original_string[end_index:]
print(new_string)
259 chars
7 lines

In this example, we first define an original string "Hello, World!" and a substring to remove ", ". We then use the find() method to find the starting index of the substring within the original string. We calculate the end index by adding the length of the substring. We then use string slicing to create a new string without the substring. The resulting string is "HelloWorld!". Note that this method requires finding the starting and ending indices of the substring, which may not always be straightforward.
