Question

Please use python 3 programming language

Write a function that gets a string representing a file name and a list. The function writes the content of the list to the file. Each item in the list is written on one line. Name the function WriteList. If all goes well the function returns true, otherwise it returns false.

Write another function, RandomRange that takes an integer then it returns a list of length n, where n is an integer passed as an argument, and the numbers in the list are random numbers in the range 1 to n inclusive.
Assume that n > 0.
For example, if the user enters 50, the RandomRange returns 50 numbers where each number is randomly generated that is >= 1 and <= 50.

Then write code for main, to get the the first input for the RandomRange function then gets the input needed for the WriteList, then call the function.
Call main.

Hi,
The following is the code for RandomRange and WriteList function according to the given instructions. I have included comments inline with the code for your reference.

I hope this answer helps you.

//Code: randfilewrite.py

import random

def RandomRange(size):
"""
Function to generate and return a list of given size. Each of the elements are random numbers between the range 1 to given number.
"""

rand_list = []
for i in range(size):   
# Get a random number between 1 and size (inclusive)
r = random.randrange(1, size+1)   

# Add to the list
rand_list.append(r)

#Return the list
return rand_list   

def WriteList(list_values):
"""
Function to write the elements of the list to a file - mylist.txt
"""
#Open the file in write mode
out_file = open("mylist.txt", "w")

#Iterate the list
for val in list_values:
#Write each element in different line to the file
out_file.write(str(val) + "\n")

out_file.close()

def main():
"""
Main method to get user's input for List size and invoke RandomRange and WriteList methods
"""   
val = input("Enter a number: ")
rand_list = RandomRange(int(val))
print("List with Random nos: " + str(rand_list))
  
print("Writing to file - mylist.txt")
WriteList(rand_list)

if __name__ == "__main__":
main()

### Output
