How to check if a python string contains another string?


Asked by Jeffery Mullen on Dec 12, 2021 FAQ



In Python there are ways to find if a String contains another string. The 'in' operator in Python can be used to check if a string contains another string. It returns true if the substring is present and it returns false if there is no match.
Just so,
Python String contains () 1 Syntax of String.__contains__ () This function will take two strings, and return if one string belongs to another. ... 2 Using String.__contains__ () We’ll check if a Python string contains another string. ... 3 Using Python String contains () as a Class method. ... 4 Conclusion. ... 5 References
Keeping this in consideration, If the item is found, this function returns the position. But if it is not found, it will return string::npos. So for checking whether the substring is present into the main string, we have to check the return value of find () is string::npos or not. Here we are simply getting the position where the substring is present.
Moreover,
A String that contains the connection string value. The following code example creates a FileSystemTask as an Executable in a package. The FileSystemTask copies a test folder that contains two subfolders and a .txt file, to another folder. The source and destinations are existing folders.
Similarly,
We’ll check if a Python string contains another string. print("String contains target!") Since “AskPython” is a substring of the original string, “Hello from AskPython”, the return value is True.
