These days string manipulation is very popular in Python, and due to it’s immutable character, sometimes, it becomes more important to know it’s working and hacks. This particular article solves the problem of deleting all occurrences of character from a string. Let’s discuss ways in which this can be achieved.
Method #1 : Using translate()
Usually this function is used to convert a particular character to some other character. By translating the resultant removal character to “None”, this function can perform this task. This function works only for Python2
# Python code to demonstrate working of # Deleting all occurrences of character # Using translate() # initializing string test_str = "GeeksforGeeks" # initializing removal character rem_char = "e" # printing original string print("The original string is : " + str(test_str)) # Using translate() # Deleting all occurrences of character res = test_str.translate(None, rem_char) # printing result print("The string after character deletion : " + str(res)) |
The original string is : GeeksforGeeks The string after character deletion : GksforGks
Method #2 : Using replace()
This function works functionally quite similar to the above function, but it is recommended due to several reasons. It can be used in newer versions of Python and is more efficient than the above function. We replace the empty string instead of None as above for using this function to perform this task.
# Python3 code to demonstrate working of # Deleting all occurrences of character # Using replace() # initializing string test_str = "GeeksforGeeks" # initializing removal character rem_char = "e" # printing original string print("The original string is : " + str(test_str)) # Using replace() # Deleting all occurrences of character res = test_str.replace(rem_char, "") # printing result print("The string after character deletion : " + str(res)) |
The original string is : GeeksforGeeks The string after character deletion : GksforGks
