How to Generate a Random Number in Python with Examples
In this program, you will learn how to write python code for random numbers. you have to import random library to generate random numbers. Then you need to call random.randint function with starting number and ending number.
It will produce the random number from with in the range.
The random number are change for each execution. you can define random.seed(123) to stable the random values.
How to generate random numbers from 0 to 1
import random
#random.seed(123)
a=random.randint(0,1)
print(a)
Output:
1
How to generate random numbers from 0 to 10:
import random
#random.seed(123)
a=random.randint(0,10)
print(a)
Output:
7
How to generate random numbers from 0 to 100
import random
#random.seed(123)
a=random.randint(0,100)
print(a)
Output:
71
If you need random matrix number for data science operations, you need import numpy library. By using numpy, you can define random numbers with mu
import numpy as np
a=np.random.randint(2,size=10)
print(a)
# 2 dimensional array
a=np.random.randint(10,size=(2,5))
print(a)
# 3 dimensional array
a=np.random.randint(10,size=(3,5))
print(a)
Output:
[0 1 1 0 1 0 0 1 0 1] [[1 9 0 8 9] [2 7 9 1 7]] [[5 2 6 3 0] [5 2 0 5 9] [2 1 1 1 5]]
