This section briefly describes the number types and basic mathematical computing in Python and the python number types.

Python has four types of numbers:
1. Integer

a = 2 print a 

2. Long Integer

b = 123456789 print b 

3. Floating Point Number

c = 3.2E2 print c 

4. the plural number is the extension of the real number, which gives root to any polynomial. In the plural, there is a "virtual number unit" j, which is a square root of-1. Any plural number can be expressed as x + yj, where x and y are real numbers, which are called "real" and "virtual" of the plural ".

d = (2+3j) print d 

 

Calculation example:
Every programming language has a mathematical calculation method and a general mathematical symbol. Go directly to the Code:

print "I will now count my chickens:"   print "Hens", 25 + 30 / 6 print "Roosters", 100 - 25 * 3 % 4   print "Now I will count the eggs:"   print 3 + 2 + 1 - 5 + 4 % 2 - 1 / 4 + 6   print "Is it true that 3 + 2 < 5 - 7?"   print 3 + 2 < 5 - 7   print "What is 3 + 2?", 3 + 2 print "What is 5 - 7?", 5 - 7   print "Oh, that's why it's False."   print "How about some more."   print "Is it greater?", 5 > -2 print "Is it greatet or equal?", 5 >= -2 print "is it less or equal?", 5 <= -2 

The running result is as follows:

root@he-desktop:~/mystuff# python ex3.py I will now count my chickens:Hens 30Roosters 97Now I will count the eggs:7Is it true that 3 + 2 < 5 - 7?FalseWhat is 3 + 2? 5What is 5 - 7? -2Oh, that's why it's False.How about some more.Is it greater? TrueIs it greatet or equal? Trueis it less or equal? False

Eg: converts inches and LBS into centimeters and kilograms in mathematical calculations.
1 inch = 2.54 cm, 1 lb = 0.4536 kg

my_height_centimeter = my_height * 2.54 my_weight_kilo = my_weight * 0.4536 print "He's %d centimeters tall." % my_height_centimeter print "He's %d kilos heavy." % my_weight_kilo
