 import random ran_dom = 0 def gen_ran(): ran_dom = round(random.random(), 5) print(ran_dom, end="\t") resp = int(input("How many randoms you want to generate :")) for i in range(resp): x = 0 for x in range(10): gen_ran() print("\r") 

If I want 50 randoms, the output is a table of 10 columns and 50 rows. Awaiting suggestions from you people. Regards, Aditya Pratap V.

import random
ran_dom = 0
def gen_ran():
    ran_dom = round(random.random(), 5)
    print(ran_dom, end="\t")

resp = int(input("How many randoms you want to generate :"))

for i in range(resp):
    if i % 10 == 0:
        print("\r")
    gen_ran()
print("\n")

>>> import random
>>> table = [[random.random() for j in range(10)] for i in range(50)]    # will create 2D matrix 50 rows with 10 elements
>>> for row in table: 
...     print(*row, sep=' ')                                             # will print row by row, row values separated by space

>>> import numpy as np
>>> np.random.rand(50,10)

More common would be to built data structure and print it out if needed:

>>> import random
>>> table = [[random.random() for j in range(10)] for i in range(50)]    # will create 2D matrix 50 rows with 10 elements
>>> for row in table: 
...     print(*row, sep=' ')                                             # will print row by row, row values separated by space

If work is getting more serious then numpy has built-in method:

>>> import numpy as np
>>> np.random.rand(50,10)
