 Tick
In Python, the time instants are counted since 12 AM, 1st January 1970. The function time() of the module time
returns the total number of ticks spent since 12 AM, 1st January 1970. A tick can be seen as the smallest unit to
measure the time.
Consider the following example
1 import time;
2 #prints the number of ticks spent since 12 AM, 1st January 1970

3 print(time.time())
Output:
1585928913.6519969

How to get the current time?
The localtime() functions of the time module are used to get the current time tuple. Consider the following exam.

Introduction
In this article, we are discussing Math Module in Python. We can easily calculate many mathematical calculations
in Python using the Math module. Mathematical calculations may occasionally be required when dealing with
specific fiscal or rigorous scientific tasks. Python has a math module that can handle these complex calculations.
The functions in the math module can perform simple mathematical calculations like addition (+) and subtraction
(-) and advanced mathematical calculations like trigonometric operations and logarithmic operations.
This tutorial teaches us about applying the math module from fundamentals to more advanced concepts with
the support of easy examples to understand the concepts fully. We have included the list of all built-in functions
defined in this module for better understanding.
What is Math Module in Python?
Python has a built-in math module. It is a standard module, so we do not need to install it separately. We only
must import it into the program we want to use. We can import the module, like any other module of Python, using
import math to implement the functions to perform mathematical operations.
Since the source code of this module is in the C language, it provides access to the functionalities of the underlying
C library. Here we have given some basic examples of the Math module in Python. The examples are written
below -
Program Code 1:
Here we give an example of a math module in Python for calculating the square root of a number. The code is
given below -
1 # This program will show the calculation of square root using the math module
2 # importing the math module
3 import math

4 print(math.sqrt( 9 ))
Output:
Now we compile the above code in Python, and after successful compilation, we run it. Then the output is given
below -
