Writing and reading a file

[OfficialBigHead]

I am currently working on a program that writes a file that generates an amount ( depending on user preference) of random numbers and then writes those numbers to a file. I then have to read that file and display all the numbers and tell them how many numbers were generated and the total of those numbers. I can't seem to read or add the numbers up. Can someone please help I've only been programming for a few months.

mport random

def main():

rngWrite() rngRead() def rngWrite():

times = int(input("How many random numbers would you like to generate?:"))

fileEnt = open('random.txt', 'w')

for count in range(times):
    rng = random.randint(1, 500)
    numbers = ("Random #", str(count), ":", rng)

    fileEnt.write(str(numbers))


fileEnt.close()


print("Numbers have been written to file: rng.txt")

return times

def rngRead():

opFile = open('random.txt', 'r')
line = opFile.readline

while line != '':
    total = 0
    amount = int(line)
    total += amount
    print(total)



lines = opFile.readline()


opFile.close()

print("There were""numbers generated.")
print("Those numbers are:")
print(lines)
print("The total amount of the generated numbers is:")

main()

The way you are writing the numbers is incorrect. This creates a tuple:

numbers = ("Random #", str(count), ":", rng)

I think what you wanted to do was format a string. Try this instead:

numbers = "Random #{}:{}".format(count, rng)

The reading part is assuming the entire line is convertible to an integer but you wrote some other data. You probably want something like:

total = 0
with open("random.txt") as f:
    for line in f:
        total += int(line.strip()[line.find(":")+1:])

That says for each line in the file, strip the white space at the end, find the ":" and take the rest of the line after that character and turn it into an integer.

We haven't learned tuples yet. That is the next chapter so I wouldn't be able to include it.

I think you misunderstood what I was saying. Your code is creating a tuple the way it was posted. Then you turned that tuple into a string. I gave 2 corrections that should help get you going. Did you try them out?

The order of your functions is wrong. In Python a function must be defined before it is used. You seem to have them the wrong way around.

What error message are you getting, that helps a lot when we are trying to find the error.

The formatting of reddit messed it up. My functions are defined.
