Python | Extract odd length words in String
  • Last Updated : 22 Apr, 2020

Sometimes, while working with Python, we can have a problem in which we need to extract certain length words from a string. This can be extraction of odd length words from the string. This can have application in many domains including day-day programming. Lets discuss certain ways in which this task can be performed.

Method #1 : Using loop
This is brute force way in which this task can be performed. In this, we first split the string to words and then perform iteration to get the odd length words.




# Python3 code to demonstrate working of 
# Extract odd length words in String
# Using loop
  
# initializing string
test_str = "gfg is best of geeks"
  
# printing original string
print("The original string is : " + test_str)
  
# Extract odd length words in String
# Using loop
res = []
for ele in test_str.split():
    if len(ele) % 2 :
        res.append(ele)
  
# printing result 
print("The odd length strings are : " + str(res)) 
Output :
The original string is : gfg is best of geeks
The odd length strings are : ['gfg', 'geeks']

 

Method #2 : Using list comprehension
This task can also be performed using list comprehension. In this, we perform the task in similar way as above. Just the difference is that its a one-liner.






# Python3 code to demonstrate working of 
# Extract odd length words in String
# Using list comprehension
  
# initializing string
test_str = "gfg is best of geeks"
  
# printing original string
print("The original string is : " + test_str)
  
# Extract odd length words in String
# Using list comprehension
res = [ele for ele in test_str.split() if len(ele) % 2]
  
# printing result 
print("The odd length strings are : " + str(res)) 
Output :
The original string is : gfg is best of geeks
The odd length strings are : ['gfg', 'geeks']
