Python – Find Words with both alphabets and numbers

  • Last Updated : 22 Apr, 2020

Sometimes, while working with Python strings, we can have problem in which we need to extract certain words with contain both numbers and alphabets. This kind of problem can occur in many domains like school programming and web-development. Lets discuss certain ways in which this task can be performed.

Method #1 : Using any() + isdigit() + isalpha()
The combination of above functionalities can be used to perform this task. In this, we iterate for all the words and check for required combination using isdigit() and isalpha().

# Python3 code to demonstrate working of 
# Words with both alphabets and numbers
# Using isdigit() + isalpha() + any()
  
# initializing string
test_str = 'geeksfor23geeks is best45 for gee34ks and cs'
  
# printing original string
print("The original string is : " + test_str)
  
# Words with both alphabets and numbers
# Using isdigit() + isalpha() + any()
res = []
temp = test_str.split()
for idx in temp:
    if any(chr.isalpha() for chr in idx) and any(chr.isdigit() for chr in idx):
        res.append(idx)
          
# printing result 
print("Words with alphabets and numbers : " + str(res)) 
Output :



The original string is : geeksfor23geeks is best45 for gee34ks and cs
Words with alphabets and numbers : [‘geeksfor23geeks’, ‘best45’, ‘gee34ks’]

 

Method #2 : Using regex
This is yet another way by which we can perform this task. In this, we feed the string to findall(), and extract the required result. Returns strings till the numbers only.




# Python3 code to demonstrate working of 
# Words with both alphabets and numbers
# Using regex
import re
  
# initializing string
test_str = 'geeksfor23geeks is best45 for gee34ks and cs'
  
# printing original string
print("The original string is : " + test_str)
  
# Words with both alphabets and numbers
# Using regex
res = re.findall(r'(?:\d+[a-zA-Z]+|[a-zA-Z]+\d+)', test_str)
          
# printing result 
print("Words with alphabets and numbers : " + str(res)) 
Output :

The original string is : geeksfor23geeks is best45 for gee34ks and cs
Words with alphabets and numbers : [‘geeksfor23’, ‘best45’, ‘gee34’]
