Question

I need help writing these 2 programs

please include all the indents :)

In this programming challenge you are to create two Python programs: randomwrite.py andrandomread.py. One program, randomwrite.py, is to write a set of random numbers to a file. The second program, randomread.py, is to read a set of random numbers from a file, counts how many were read, displays the random numbers, and displays the total count of random numbers.

Random Number File Writer (randomwrite.py)

Create a program called randomwrite.py that writes a series of random integers to a file. The program is to request from the user how many random numbers to generate, the lower bound of the random numbers’ range, and the upper bound of the random numbers’ range. Each random integer value is to be on a separate line and is to be in the range of the inputted lower bound through the inputted upper bound. The file that the random numbers are written to is to be called randomnum.txt.

The user input is to be safe from crashes from invalid input. The user must enter a positive number for all required input (quantity of random numbers to generate, the lower bound of the random numbers’ range, and the upper bound of the random numbers’ range). If invalid input is received the user is to be given feedback and provided with the ability to enter a value again. A positive number is not zero and not negative. The program must not crash if an error occurs during a file operation. Use exception handling.

These are the same requirements for this program:

• The program should accept user input for the quantity of random numbers to generate.
• The inputted number should be a positive integer.
• The program should accept user input for the lower bound of the random numbers’ range.
• The inputted number should be positive integer.
• The program should accept user input for the upper bound of the random numbers’ range.
• The inputted number should be positive integer.
• User input may not cause the program to crash. Exceptions from invalid user input must be handled gracefully. The user is to be given feedback about invalid input and given the opportunity to supply the input without needing to run the program again.
• The program should generate the user supplied amount of random integer numbers between the user supplied lower and upper bound range.
• The random integers should be written to a file called called randomnum.txt with each random integer being on a separate line.

Example:

How many random numbers do you want? 10
What is the lowest the random number should be: 1
What is the highest the random number should be: 10
The random numbers were written to randomnum.txt

Program 2: Random Number File Reader (randomread.py)

Create a program called randomread.py that reads a series of random numbers from a file calledrandomnum.txt, counts how many there are, displays the random numbers, and displays the count.

The output to the user is to be labeled and nicely formatted. Prior to displaying the random numbers display the string List of random numbers in randomnum.txt: Each random number is to be displayed on a separate line. The count displayed to the user is to be preceded with the string Random number count:.

Example:

List of random numbers in randomnum.txt:
5
45
32
15

Random number count: 4

The program must not crash if an error occurs during a file operation. Use exception handling. For example, if randomread.py is run and there is no randomnum.txt file the program should handle the exception that occurs when attempting to open the file.

Answer : please up vote or comment for any query i will update the same .Thanks

Note : check images for indentation and output

Program Plan : randomwrite.py

1. ran three loop to take input RandomNumber,Lower Bound,UpperBound and check in while loop for validation

2. now open a file generate random number and write to write in a new line

3. handle exception

Program plan : randomread.py

1. open a file and hand;e file opening exceptions

2. read line by line and check for integer and increase count by 1

3. display number of count

Program : randomwrite.py

import random
RandomNumber=0
LowerBound=0
UpperBound=0
while(RandomNumber<=2): #get user input till random number is less than 3
RandomNumber=input("How many random numbers do you want? ")

while(LowerBound<=0): #lower random number should be greater than 0
LowerBound=input("what is the lowest random number should be? ")

while(UpperBound<=LowerBound): #upper number should greater than lower
UpperBound=input("what is the highest random number should be? ")

i=0
try:
fh = open("randomnum.txt", "w") #open
while i in range(RandomNumber): # zero to number of random number
RandomNum=random.randint(LowerBound,UpperBound) #range between lower and upper
fh.write(str(RandomNum)) #convert int to string and write
fh.write("\n") #new line
i+=1
  

except IOError: #throw exception
print "Error: can\'t find opening error"
else:
print "Written content in the file successfully"
fh.close()

Program : randomread.py

import os
count=0
fname="randomnum.txt" #file name
if os.path.exists(fname): #check file exist or not
with open(fname, 'rb') as f: #open fle

try:

count = 0
for line in f: #read line by line
try:
if(int(line)):
count += 1 #if line have integer increase count
except ValueError: #throw exception integer not found
pass
else:
pass

except IOError:
print ("Could not read file:", fname) #unable to read
else:
print("Random number count : ",count)
else:
print("file not found")
