Sometimes, while working with Python, we can have a problem in which we need to check for perfection of data in list. One of parameter can be that each element in list is non-empty. Let’s discuss if a list is perfect on this factor using certain methods.
Method #1 : Using any() + len()
The combination of above functions can be used to perform this task. In this, we use any() to check for any element in string and len() is used to get if length of any string is 0 or not.
# Python3 code to demonstrate working of # Check if any String is empty in list # using len() + any() # initialize list test_list = ['gfg', 'is', 'best', '', 'for', 'geeks'] # printing original list print("The original list : " + str(test_list)) # Check if any String is empty in list # using len() + any() res = any(len(ele) == 0 for ele in test_list) # printing result print("Is any string empty in list? : " + str(res)) |
The original list : ['gfg', 'is', 'best', '', 'for', 'geeks'] Is any string empty in list? : True
Method #2 : Using in operator
This task can also be performed using in operator. This checks internally for all strings in list and returns True if we find any empty string.
# Python3 code to demonstrate working of # Check if any String is empty in list # using in operator # initialize list test_list = ['gfg', 'is', 'best', '', 'for', 'geeks'] # printing original list print("The original list : " + str(test_list)) # Check if any String is empty in list # using in operator res = '' in test_list # printing result print("Is any string empty in list? : " + str(res)) |
The original list : ['gfg', 'is', 'best', '', 'for', 'geeks'] Is any string empty in list? : True
