Random function usage notes

1. Import random modular

import  random

2. Generate (n, m) Random integer between

>>> import random
>>> a = random.randint(1, 10)     #1<=a<=10 And n,m Size must be n<m
>>> print(a)
3
>>> 

3. take 0-1 Between random floating-point numbers

>>> import random
>>> a = random.random()
>>> print(a)
0.7513964072198035     # Default 15-16 digit 
>>>

4. Generate (n, m) Is a random floating point number

>>> import random
>>> a = random.uniform(1, 3)
>>> print(a)
1.750766501474142
>>> a = random.uniform(3, 1)    #n,m The size can be reversed 
>>> print(a)
2.067256580652267
>>> 

5. Generate (n, m) Is a random floating point number , The decimal point is x position

>>> import random
>>> a = random.uniform(1, 10)
>>> b = round(a, 2)   #x=2
>>> print(b)
4.55
>>>
