Python in how to operate Integer integer and Float floating-point, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

First, create a new python file named py3_integer_float.py, and code the string manipulation in this file:

# define a variable and assign it to 3num = "use the type () function to view the type of num # the result is print (type (num)) # then assign the num to 3.3" and then print the object type num = 3.3 "and the result is print (type (num)) # basic arithmetic # addition: 3 + subtraction: 3-multiplication: 3 * Division: 3 / floor division: 3 / floor division The remainder of "exponentiation: 3 * *": 3% 2print (3 + 2) # 5print (3-2) # 1print (3 * 2) # 6print (3x2) # 1.5print (3 / / 2) # 1print (3 * * 2) # 9print (3% 2) # "about division 3ripple" runs in the python2 version and the result is the real result # the order of arithmetic operations # the basic principle is # multiply and divide first Add and subtract # the following example first calculates 3 times "add 1print (3 * 2 + 1) #" with the following modifications # if enclosed in parentheses # will first calculate the contents in parentheses # so the result is 9print (3 * (2 + 1)) # the number grows num = 1num = num + 1print (num) # "or + = way num = 1num + = 1print (num) # use * = num = 1num * = 5print (num) # built-in function # abs (): take absolute value print (abs (- 7)) # 7#round (): rounding count print (round (5.75)) # 6#round () keep decimal places print (round (5.75)) # 5." comparison operator # results return Boolean type value True/False# equals: 3 = "not equal to: 3! =" greater than: 3 > "< 3:

= less than or equal to: 3 2) # Trueprint (3

= 2) # Trueprint (3
