How to Import Files in Python

Python is an interactive and more accessible language than any other programming language. The python programming language uses a variety of libraries to perform the operations in a faster way. The python language can also be used in web development; Django and Flask are the frameworks used to create web applications using Python. In Python, indentation is the main concept; if we do not follow proper indentation, then the program will not run properly, and we will get an error in the output. Python programming language contains methods or functions to reduce the size of the code, and the python programming language provides built-in functions and user-defined functions.

We can import the functions in the python programming language through the libraries, which can be downloaded using the python package manager ( pip ). While working on the project and we want to develop the project using the python programming language. The python programming language makes our work easy by providing built-in functions, with these imported using the # import. The import statement is used to impost the modules or built-in functions into the program so we can develop the project easily and faster.

Import File in a Python

The python programming language makes our work easy by providing built-in functions with these imported using the # import. The import statement is used to impost the modules or built-in functions into the program so that we can develop the project quickly and quickly. The python programming language provides us with the “matplotlib” library, which is used to perform mathematical operations. The python programming language provides us with all these definitions and the functions inside a file known as the modules; these modules help us to perform the operation in an interactive and faster way. Using the import statement, we can import these functions inside the program or another module.

While saving a file in the python programming language as a module, we need to save the module with the suffix .py; we can save the module name using the name of the string. Now let us consider an example of the multiplication of two numbers, we can save this file as mul.py, and we can import this module into any program where we require the multiplication of the two numbers. We can reduce the size of the code.

Program:

# Mul.py
def multiply( x, y)
       z= x * y
return z

Here we can observe that the Mul.py function contains the multiply function, which takes two parameters as the input, and in return, it will provide us with the product of the two numbers; whenever we import this Mul.py file, it will give us the product of two numbers in the output and will return their product value as the return value.

# importing the file Mul.py
importMul

This Mul will perform the required operation and return the product's result at the output so that our code has become more efficient and the size of the code is reduced.

Import statement syntax:

import  module_name

Parameters:

module_name: The name of the module that needs to be imported to perform the required operations.

Now let us consider an example in which the module_name is Mul, which will perform the multiplication of the given two numbers and will return the result.

Code:

#importing the Mul to use the multiply( ) function
importMul
# display the product of two numbers
print(Mul.multiply(2, 4))

Output:

8

If we want to use the multiply( ) function greater than once in the program, we need to create a local variable and store the second function in that variable.

Code:

#importing the Mul to use the multiply( ) function
importMul


# creating the new variable
product = Mul.multiply
# display the product of two numbers
print( product(2, 4))

Output:

8

Here we can observe thatwe have assigned the multiply( ) function to a new variable product and displayed the product of the two numbers at the output.

Python modules can be imported into another module to perform various operations in a program to perform various operations. The modules in Python contain the definitions and the functions to perform the executable statements.
