Input inputs: input (hint information) is typed in string type

Conversion: Int (variable) float (variable) str (variable)

String decimals cannot be converted to integral type
b = "12.33" b = int (b) Error
Floating-point type can be converted to integral type
b = 12.33 B = Int (b) No problem

Two number swaps
A = 10
b = 20
A, B = b,a

Power to fetch quotient

Python xor, bitwise, and

Priority: () > Arithmetic > Compare > Logic > Assignment + = 、...、%=,//= calculation assignment

If statement judgment, two number comparison without float type float

If, if else, if elif if

Random number generation
Import Random
n = random.randint (0,2) # [0,2] 0-2 generate random number
