Random Choice of Random Module in Python with no Repeat

Given the upper limit and lower limit, the task is to generate n natural numbers which are not repeating in Python.

Examples:

Example1:

Input:

Given N=13
Given lower limit range =19
Given upper limit range =45

Output:

The random numbers present in the range from 19 to 45 are :
28 40 24 25 20 44 38 29 21 31 43

Example2:

Input:

Given N=19
Given lower limit range =23
Given upper limit range =41

Output:

The random numbers present in the range from 23 to 41 are : 26 27 40 38 37 41 30 35 36 23 25

Random choice of Random module in Python with no Repeat

Below are the ways to generate n natural numbers which are not repeating in Python.

Using For loop and randint function(Static Input)
Using For loop and randint function (User Input)

Practice Java programming from home without using any fancy software just by tapping on this Simple Java Programs for Beginners tutorial.

Method #1: Using For Loop and randint function (Static Input)

Approach:

Import the random module using the import keyword.
Give the number n as static input and store it in a variable.
Give the lower limit range and upper limit range as static input and store them in two separate variables.
Take an empty list (say rndmnumbs) and initialize it with an empty list using [] or list().
Loop till n times using For loop.
Generate a random number using randint(lowerlimitrange,upperlimitrange) and store it in a variable.
Check whether the above random number is present in the list or not using not in operator.
If it is not in the list then append the element to the rndmnumbs list using the append() function.
Print the rndmnumbs.
The Exit of the Program.

Below is the implementation:

# Import the random module using the import keyword.
import random
# Give the number n as static input and store it in a variable.
numbe = 13
# Give the lower limit range and upper limit range as static input
# and store them in two separate variables.
lowerlimitrange = 19
upperlimitrange = 45
# Take an empty list (say rndmnumbs) and initialize it with an empty list
# using [] or list().
rndmnumbs = []
# Loop till n times using For loop.
for m in range(numbe):
        # Generate a random number using randint(lowerlimitrange,upperlimitrange)
    # and store it in a variable.
    randomnumbe = random.randint(lowerlimitrange, upperlimitrange)
    # Check whether the above random number is present in the list or not
    # using not in operator.
    if randomnumbe not in rndmnumbs:
        # If it is not in the list then append the element
        # to the rndmnumbs list using the append() function.
        rndmnumbs.append(randomnumbe)

# Print the rndmnumbs
print('The random numbers present in the range from',
      lowerlimitrange, 'to', upperlimitrange, 'are :')
for q in rndmnumbs:
    print(q, end=' ')

Output:

The random numbers present in the range from 19 to 45 are :
28 40 24 25 20 44 38 29 21 31 43

Method #2: Using For Loop and randint function (User Input)

Approach:

Import the random module using the import keyword.
Give the number n as user input using int(input()) and store it in a variable.
Give the lower limit range and upper limit range as user input using map(),int(),split(),input() functions.
Store them in two separate variables.
Take an empty list (say rndmnumbs) and initialize it with an empty list using [] or list().
Loop till n times using For loop.
Generate a random number using randint(lowerlimitrange,upperlimitrange) and store it in a variable.
Check whether the above random number is present in the list or not using not in operator.
If it is not in the list then append the element to the rndmnumbs list using the append() function.
Print the rndmnumbs.
The Exit of the Program.

Below is the implementation:

# Import the random module using the import keyword.
import random
# Give the number n as user input using int(input()) and store it in a variable.
numbe = int(input('Enter some random number = '))
# Give the lower limit range and upper limit range as user input
# using map(),int(),split(),input() functions.
# Store them in two separate variables.
lowerlimitrange = int(input('Enter random lower limit range = '))
upperlimitrange = int(input('Enter random upper limit range = '))
# Take an empty list (say rndmnumbs) and initialize it with an empty list
# using [] or list().
rndmnumbs = []
# Loop till n times using For loop.
for m in range(numbe):
        # Generate a random number using randint(lowerlimitrange,upperlimitrange)
    # and store it in a variable.
    randomnumbe = random.randint(lowerlimitrange, upperlimitrange)
    # Check whether the above random number is present in the list or not
    # using not in operator.
    if randomnumbe not in rndmnumbs:
        # If it is not in the list then append the element
        # to the rndmnumbs list using the append() function.
        rndmnumbs.append(randomnumbe)

# Print the rndmnumbs
print('The random numbers present in the range from',
      lowerlimitrange, 'to', upperlimitrange, 'are :')
for q in rndmnumbs:
    print(q, end=' ')

Output:

Enter some random number = 19
Enter random lower limit range = 23
Enter random upper limit range = 41
The random numbers present in the range from 23 to 41 are :
26 27 40 38 37 41 30 35 36 23 25
