Hello Everyone,
I got some cool stuff to share with you all. This tips will benefit those who just started exploring python. I kept things quite simple and straight forward for anyone to understand. Plus you can bookmark this blog page for your future reference in-case you forget something or get stuck.
So moving on with the code...
💥TOP 10 Python - Fun with Numbers💥
1) Creating variables in one line in python.
1 2 3 4 | >>> #_1 creating variables in one line in python >>> a = 5; b = 10; c = a; d = a**2 ; e = d + 10 >>> print(a,b,c,d,e) 5 10 5 25 35 |
2) Multiplying text with integer (number) in python.
1 2 3 4 | >>> #_2 multiplying text with integer (number) in python >>> a = 5 >>> print (a*'pysnake') pysnakepysnakepysnakepysnakepysnake |
3) Multiplying text with space in python.
1 2 3 4 | >>> #_3 multiplying text with space in python >>> a = 5 >>> print (a*'pysnake ') pysnake pysnake pysnake pysnake pysnake |
4) Multiplying text with line break '\n' in python.
1 2 3 4 5 6 7 8 | >>> #_4 multiplying text with line break '\n' in python >>> a = 5 >>> print (a*'pysnake\n') pysnake pysnake pysnake pysnake pysnake |
5) Print simple text with integer (tuple) in python.
1 2 3 4 | #_5 print simple text with integer (tuple) in python >>> a = 5 >>> print(a,'pysnake') 5 pysnake |
6) Python as a Calculator.
1 2 3 4 5 6 7 8 9 10 11 12 13 | >>> #_6 python as a Calculator >>> # Using Simple Operators:- [ + - * / ] >>> print(8+6, 20-7, 9*8, 7/2) 14 13 72 3.5 >>> >>> # Using floor functionality Operators:- [ % // ** ] >>> print(8%6, 20//7, 9**8) 2 2 43046721 >>> >>> # Using parentheses '( )' order of execution:- [ ( ) ] >>> print(25 - 3 / (7 % 2)) 22.0 >>> |
7) Using two main types of numbers in python i.e. 'int' (integer) & 'float' (numbers with decimal point).
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | #_7 using two main types of numbers in python i.e. 'int' (integer) & 'float' (numbers with decimal point) >>> planets = 12 >>> print(type(planets)) <class 'int'> >>> >>> pie = 3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342117067 >>> print(type(pie)) <class 'float'> >>> >>> # adding the two variables >>> planets_pie = planets + pie >>> print(planets_pie) 15.141592653589793 >>> >>> # convert to int >>> print(int(planets_pie)) 15 >>> >>> # convert to float >>> print(float(planets_pie)) 15.141592653589793 |
8) Using input function in python.
1 2 3 4 5 | >>> #_8 using input function in python >>> my_int = int(input("Enter a number:- ")) Enter a number:- 8 >>> print("Today's lucky number is..... :-",my_int) Today's lucky number is..... :- 8 |
9) Importing modules (Addons for Python). Reason:- For more functionality & faster calculation.
1 2 3 4 5 6 7 8 9 10 11 12 | >>> #_9 importing modules (Addons for Python). Reason:- For more functionality & faster calculation >>> # we will appoint import 'math' with 'm' & 'degrees' as 'd' as short hand word/words >>> import math as m >>> from math import degrees as d >>> print(m.sin(90)) 0.8939966636005579 >>> >>> print(m.cos(90)) -0.4480736161291701 >>> >>> print(m.tan(90)) -1.995200412208242 |
9.1) Printing Pie
1 2 3 | >>> # printing pie >>> print(m.pi) 3.141592653589793 |
