Python has support for both mathematical operations and functions.

Mathematical operations
An overview of operations:

Mathematical functions
Python supports a wide variety of mathematical functions.

Operation	Result
x + y	sum of x and y.
x * y	multiplication of x and y.
x - y	difference of x and y.
x / y	division of x by y.
x % y	remainder of x/y
x ** y	x to the power of y
abs(x)	absolute value of x
sqrt(x)	square root of x

Tip
You can use the Python interpreter as calculator. To do so you simply start Python without an IDE and filename. Example:


  Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.

Function	Returns	Example
abs(x)	Returns the absolute value of x.	{% codeblock lang:python line_number:false %} x = -35 x = abs(x) print(x) {% endcodeblock %}
cmp(x,y)	Returns -1 if x < y Returns 0 if x equals to y Returns 1 if x > y.	{% codeblock lang:python line_number:false %} x = 6 y = 4 print( cmp(x,y) ) {% endcodeblock %}
exp(x)	Returns the exponential of x	{% codeblock lang:python line_number:false %} import math x = 6 print( math.exp(x) ) {% endcodeblock %}
log(x)	The natural logarithm of x	{% codeblock lang:python line_number:false %} import math x = 6 print( math.log(x) ) {% endcodeblock %}
log10(x)	The base-10 logarithm of x	{% codeblock lang:python line_number:false %} import math x = 6 print( math.log10(x) ) {% endcodeblock %}
pow(x,y)	The result of x**y	{% codeblock lang:python line_number:false %} import math x = 6 print( math.pow(x,2) ) {% endcodeblock %}
sqrt(x)	The square root of x	{% codeblock lang:python line_number:false %} import math x = 6 print( math.sqrt(x) ) {% endcodeblock %}
