How to concatenate strings in Python

Python is likely one of the best programming languages to get to grips with, and additionally one of the crucial robust and in-demand. Finding out Python is not just amusing then, but additionally a unbelievable occupation transfer. Some of the first ideas you’ll want to make yourself familiar with to that finish is how to use strings. On this publish, you’ll find out how to create, exchange, and concatenate strings in Python.

So… what’s a string?

When you’re scratching your head, a string is a variable that represents a sequence of alphanumeric characters and symbols. This may well be a title, a phrase, or a complete sentence.

Strings are helpful when you wish to have to display textual content at the display screen that would possibly exchange in reaction to consumer enter. They’re additionally helpful for storing information: for example names in a database.

If Python reveals a fit, then it is going to go back the index of that substring. If it doesn’t to find it, it is going to go back the price “-1”.
