In this example, we loop through each string in the list using a for loop. For each string, we use the in operator to check if the substring is present. If we find a match, we return True, indicating that the substring is present in at least one string. If no match is found ...

we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...
If there are two arguments, they must be strings of equal length, and in the resulting dictionary, each character in x will be mapped to the character at the same position in y. If there is a third argument, it must be a string, whose characters will be mapped to None in the result...

5. String Methods – Getting Substring of String Python provides several built-in string methods that can be used to extract substrings from a string. These methods offer more flexibility than slicing, as they allow you to search for specific patterns within the string and extract substrings bas...
In Python, many times when you're working with substrings you want to find whether a substring is inside another string or not, there can be many reasons for
