Import Statements and Assertion Tricks in Python

Import Statements and Assertion Tricks in Python

In Python, the import statement is a powerful tool for bringing functions, classes, or variables defined in other modules into the current module. This allows Python programmers to take full advantage of existing code bases and use them to build more complex and powerful applications.

The import statement can be used in the following forms:

import module_name
from module_name import object_name
import module_name as alias_name

For example, we want to import Python's math library to perform some mathematical calculations:

import math

print(math.pi)

This will output the value of pi. In this example, we use the import statement to bring in the math module and use the . operator to access the pi constant defined there.

In addition, assertion (assertion) is also one of the commonly used techniques in Python. It allows the programmer to define a set of conditions, if
