Python | Extract odd length words in String
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 stringtest_str = "gfg is best of geeks" # printing original stringprint("The original string is : " + test_str) # Extract odd length words in String# Using loopres = []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 stringtest_str = "gfg is best of geeks" # printing original stringprint("The original string is : " + test_str) # Extract odd length words in String# Using list comprehensionres = [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']
