Python has several methods to deal with strings. In this tutorial, I’ll show you how to know if a string contains a substring. How to check if a string contains a substring No matter whether it’s just a word, a letter or a phrase that you want to check in a string, with Python...
2. Check String is Empty using len() The Pythonlen()is used to get the total number of characters present in the string and check if the length of the string is 0 to identify the string is empty. Actually, thelen()function returns the length of an object. The object can be a string...
Opened in python/mypy#4040, but moved here after @JukkaL 's advice. Some debate took place in there, but I'll copy the original post here for context: It's a common practice to pass literal strings as arguments. In Python, it's even more...
