Integral type operation, subtraction:

2 + 242*362-11
12/5
2
#假如想要使返回的结果为浮点数, they can be written in the form of floating-point numbers.
12.0/5.0
2.4

Power Index:

3**29

Residual:

22%52

Use type() functions to view variable types:

A = 1TPE (a) int

Floating point number (float):

A = 1.34type (a) float

Interactive calculation:

1 + 2-(3 * 4/6) * * 5 + 7% 5-27# in Python, precedence is the order of arithmetic, such as "first multiplication plus minus" and "first parentheses" are two priority rules, the priority from high to low ranked as follows: 1. () Brackets 2. * * Power exponential operation 3. *///% multiplication, except, integer division, remainder operation 4. ' +-' plus minus

Integer division, which returns the maximum integer value that is smaller than the result:

12.3//5.2   2.0

Simple Mathematical functions:

Absolute:

　　

ABS (-251.451) 251.451

Rounding:

Round (22.3) 22

Maximum minimum value:

Print min (2, 3, 4, 5) 2print Max (2, 4, 3) 4

Type conversions:

Floating-point integer, which retains only the integral part:

print int (12.324) 12print int (-3.32)-3

In situ calculation:

b = 2.5b + = 2print b4.5b *=29

Boolean type:

A Boolean can be considered a special two-value variable with a value True of False :

Q = Truetype (q) BOOLQ = 1 > 2print qfalse
