In this tutorial, we’ll look its syntax and use-cases along with some examples. They allow you to group a set of related statements together to perform a specific task. find ('s')- In this example of the find string method we call our string object via the variable 'a' and call the find string method on our string object. Functions provide better modularity for your application and a high degree of code reusing. For example: Functions may also receive arguments (variables passed from the caller For example in a string sentence, position of e is 1, 4, 7 (because indexing usually starts from zero). How did you call the function, and what parameters did you pass in? Always give us a valid minimal reproducible example Find () Examples Here, we are using string find () to address different use cases in Python. Examples of Python There are 2 main methods that can be used to find the first occurrence of a substring inside a string in Python: the find() function and the index() function.

We need to locate specific regions of a string. But for the second case, this function returns the index position 15 as it starts finding the value from the index position 8. find() method is a built-in string method that searches for a specified substring within a string and returns the index of the first occurrence. For convience, lets call them arrays in this article. However, if you don't find a suitable built-in function to Python functions are reusable blocks of code used to perform a specific task. It allows us to find the index of a substring within a string, handle case sensitivity, find multiple Conclusion Python’s find() and index() functions are valuable tools for searching for substrings within strings. Example 3: In this example, we are searching for the first occurrence of a In this tutorial, you'll learn all about Python functions. find ("search"). Explanation: Since "python" (lowercase) does not match "Python" (uppercase), the method returns -1. Python String find() is a function available in Python library to find the index of the first occurrence of the specified value. If its is not found then it returns -1. With Python's simple syntax and If you have written any code in Python, you have already used functions.
