Python | Ways to remove numeric digits from given string

Given a string (may contain both characters and digits), write a Python program to remove the numeric digits from string.

Let’s discuss the different ways we can achieve this task.

Method #1: Using join and isdigit()

# Python code to demonstrate
# how to remove numeric digits from string
# using join and isdigit
  
# initialising string
ini_string = "Geeks123for127geeks"
  
# printing initial ini_string
print("initial string : ", ini_string)
  
# using join and isdigit 
# to remove numeric digits from string
res = ''.join([i for i in ini_string if not i.isdigit()])
  
# printing result
print("final string : ", res)

                        filter_none









Output:


initial string :  Geeks123for127geeks
final string :  Geeksforgeeks





 

 Method #2: Using translate and digits













                                    filter_none

                                    close




                                    play_arrow




                                    link

                                    brightness_4

                                    code
                                




















# Python code to demonstrate 


# how to remove numeric digits from string 


# using translate 


from string import digits 


  


# initialising string 


ini_string = "Geeks123for127geeks"


  


# printing initial ini_string 


print("initial string : ", ini_string) 


  


# using translate and digits 


# to remove numeric digits from string 


remove_digits = str.maketrans('', '', digits) 


res = ini_string.translate(remove_digits) 


  


# printing result 


print("final string : ", res)

Output:


initial string :  Geeks123for127geeks
final string :  Geeksforgeeks





 

 Method #3: Using filter and lambda











                                    filter_none




                                    edit

                                    close




                                    play_arrow




                                    link

                                    brightness_4

                                    code
                                




















# Python code to demonstrate 


# how to remove numeric digits from string 


# using filter and lambda 


  


# initialising string 


ini_string = "akshat123garg"


  


# printing initial ini_string 


print("initial string : ", ini_string) 


  


# using filter and lambda 


# to remove numeric digits from string 


res = "".join(filter(lambda x: not x.isdigit(), ini_string)) 


  


# res = ini_string 


# printing result 


print("final string : ", str(res)) 



















                        chevron_right







                        filter_none









Output:


initial string :  akshat123garg
final string :  akshatgarg
