Python Tutorial #26 - Numbers, Type Conversion and Mathematics in Python Programming for Beginners
In this video by Programming for beginners we will see Numbers, Type Conversion and Mathematics in Python Programming for Beginners, in Python tutorial for beginners series.
Python programming language is very easy to learn for students and professionals.
In Python, The number data types are used to store the numeric values.
Python supports integers, floating-point numbers and complex numbers. They are defined as int, float, and complex classes in Python.
int - holds signed integers of non-limited length
float - holds floating decimal points and it's accurate up to 15 decimal places
complex - holds complex numbers
Number Systems
The numbers we deal with every day are of the decimal (base 10) number system.
But computer programmers need to work with binary (base 2), hexadecimal (base 16) and octal (base 8) number systems.
Binary - 0b or 0B
Octal - 0o or 0O
Hexadecimal - 0x or 0X
Type Conversion in Python
In programming, type conversion is the process of converting one type of number into another.
Operations like addition, subtraction convert integers to float implicitly (automatically), if one of the operands is float. For example,
print(1 + 2.0) # prints 3.0
Explicit Type Conversion
We can also use built-in functions like int(), float() and complex() to convert between types explicitly.
Python Mathematics
Python offers the math module to carry out different mathematics like trigonometry, logarithms, probability and statistics, etc. For example,
import math
print(math.pi)
print(math.cos(math.pi))
print(math.exp(10))
print(math.log10(1000))
print(math.sinh(1))
print(math.factorial(6))
