Python String Functions With Examples

Python String Functions With Examples. A Python program to print the string using function. In this program, we can print the string using a function in python. A Python function is a set of instructions. You must call a function in order to run its code. A return statement can be used to return a value from a function. Functions are a characteristic that all programming languages have in common. They enable programmers to create code blocks that execute certain tasks.

x = "inlarn"
def func():
print("welcome to " + x)
func()

 

Output:

welcome to inlarn

Function in Python

A function is a piece of code that only executes when called. If a return statement is given, Python functions return a value. After a function has been defined, it may be invoked from anywhere. A function accomplishes nothing on its own. There are primarily two kinds of functions. User-defined functions – User-defined functions are those that the user defines to fulfill a specified purpose. Built-in functions – Python’s built-in functions are those that are pre-defined.

def() Function in Python

Defining a function in Python is done as follows. The term def is used to define a function. In this case, the function name is followed by parameter(s) (). The colon: indicates the beginning of the function body, which is denoted by an indentation. The return statement determines the value to be returned within the function body. The function header begins with the keyword def. A function name that is unique to the function. The rules for naming functions in Python are the same as those for writing identifiers. Parameters (arguments) are values that we pass to a function. With this program we can execute python string using function
