How to Remove a Substring from a String in Python?

A substring is a chain of sequential characters inside a bigger string. Removing a substring from a fixed of strings deletes this substring from every detail within the set.Use str.replace() inside a for-loop to get rid of a substring from all strings in a fixed set of strings.

Use str.replace(old, new) with new as "" to remove substring old from str.

`_string = "programming"

new_string = a_string.replace("ing", "")

print(new_string)

Output

programm
`
Use str.replace() in a for loop to remove a substring from all elements in the set. Add each modified string to a new set.

string_set = {"learning", "enjoying", "programming"}

new_set = set()


for a_string in string_set:

    new_string = a_string.replace("ing", "")

    new_set.add(new_string)


print(new_set)

Output

{'enjoy', 'learn', 'programm'}
