Python | Ways to remove numeric digits from a given string



Let`s discuss the different ways to accomplish this.

Method # 1: Using join and isdigit()

# Python code for demonstration
# how to remove numeric digits from a string
# using join and isdigit

 
# initialization string

ini_string = "Geeks123for127geeks"

 
# print the initial ini_string

print ( "initial string:" , ini_string)

  
# using join and isdigit
# remove numeric digits from string

res = `` .join ([i for i in ini_string if not i.isdigit ()])

 
# print result

print ( "final string:" , res)

Exit:

 initial string: Geeks123for127geeks final string: Geeksforgeeks  

Method # 2: Using Translation and Numbers

 

# Python code for demonstration
# how to remove numeric numbers from string
# using translation

from string import digits

  
# initialization string

ini_string = " Geeks123for127geeks "

  
# print the initial ini_string

print ( "initial string:" , ini_string)

 
# using translation and numbers
# remove numeric digits from string

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

res = ini_string.translate (remove_digits)

 
# print result

print ( "final string:" , res)

Output:

 initial string: Geeks123for127geeks final string: Geeksforgeeks 

Method # 3: Using filter and lambda

# To e Python for demonstration
# how to remove numeric digits from a string
# using a filter and lambda

 
# initialization string

ini_string = "akshat123garg"

 
# print start line ini_string

print ( "initial string:" , ini_string)

 
# using filter and lambda
# remove numeric digits from string

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

 
# res = ini_string
# print result

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

Exit :

 initial string: akshat123garg final string: akshatgarg
