Python generates 10 random numbers

This article mainly introduces the method of generating random numbers in Python. Friends in need can refer to it.

If you don’t understand the relationship between generating random numbers in Python and the most commonly used functions in the random module, the following article is about generating random numbers in Python I hope you will gain something from the relationship with the most commonly used functions in the random module. The following is the introduction of this article.

random.random() is used to generate a random number of character points within a specified range. One of the two parameters is the upper limit and the other is the lower limit. If a > b, generate a random number

n: a <= n <= b。如果 a 
      
is used to generate an integer within the specified range. The parameter a is the lower limit, and the parameter b is the upper limit. Python generates random numbers
      
print random.randint(12, 20) #生成的随机数n: 12 <= n <= 20 print random.randint(20, 20) #结果永远是20 #print random.randint(20, 10) #该语句是错误的。
      
The lower limit must be less than the upper limit.
      
random.randrange
      
From the set within the specified range, incremented by the specified base, this article is a partial introduction to the application of python to generate random numbers.
      
Random integer:
      
>>> import random >>> random.randint(0,99)
      
21

      
Randomly select an even number between 0 and 100:
      
>>> import random >>> random.randrange(0, 101, 2)
      
42

      
Random floating point number:
      
>>> import random >>> random.random()
      
0.85415370477785668

      
>>> random.uniform(1, 10)
      
5.4221167969800881
      
Random character:
      
>>> import random >>> random.choice('abcdefg&#%^*f')
      
'd'
