The Python import keyword is used import modules. The modules can be accessed from another module by importing file/functions using import.

Usage

Following is the usage of the Python import keyword −

import <module_name>

Where, module_name is the name of the module we need to import.

Example

Following is an basic usage of the Python import keyword −

import array
myArray = array.array('i',[1, 2, 3, 4, 5])
print(myArray)

Output

Following is the output of the above code −

array('i', [1, 2, 3, 4, 5])

Using the 'import' Keyword with 'from'

We can use import keyword along with from to import a module.

Example

Following is an example of the usage of import along with from −

from math import sqrt, pow
# Using the imported functions
print("Square root of 99 is:", sqrt(99))  
print("7 to the power of 3 is:", pow(7, 3))

Output

Following is the output of the above code −

Square root of 99 is: 9.9498743710662
7 to the power of 3 is: 343.0

Using 'import' with asterisk (*)

The import keyword not only import a particular function but also all the functions of the module can be imported by using asterisk[*]. To import all the functions of a module, the import keyword followed by module-name and asterisk.

Example

Here, we have imported all the functions of math module using import and asterisk −

from math import *
print("The exponential value of e power 0:", exp(0))
print("The gcd of 3 and 6 :",gcd(3,6))

Output

Following is the output of the above code −

The exponential value of e power 0: 1.0
The gcd of 3 and 6 : 3

Using 'import' Keyword with 'as'

We can also use as keyword along with import to make a selected name for a particular function.

Example

Following is an example of, usage of import keyword along with as keyword −

from array import array as arr
myArray = arr('i',[10, 20, 30, 40, 50]) 
print(myArray)

Output

Following is the output of the above code −

array('i', [10, 20, 30, 40, 50])
