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()

Python3

# 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)

Method #2: Using translate and digits

Python3

# 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)

Method #3: Using filter and lambda

Python3

# 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))

Method#4 Using join() and isalpha() 

Python3

# Python code to demonstrate
# how to remove numeric digits from string
# using join and isalpha

# initialising string
str1 = "Geeks123for127geeks"

# printing initial ini_string
print("initial string : ", str1)

# using join and isaplha
# to remove numeric digits from string
str2 = "".join(x for x in str1 if x.isalpha())

# printing result
print("final string : ", str2)

Output

initial string :  Geeks123for127geeks
final string :  Geeksforgeeks

Method#5: Using loop and in 

Python3

# Python code to demonstrate
# how to remove numeric digits from string
# using loop and in

# initialising string
str1 = "Geeks123for127geeks"

# printing initial ini_string
print("initial string : ", str1)

# using loop and in
# to remove numeric digits from string
num = "1234567890"
str2 = ""
for i in str1:
    if i not in num:
        str2+=i

# printing result
print("final string : ", str2)

Output

initial string :  Geeks123for127geeks
final string :  Geeksforgeeks
