Searching a CSV file in Python - IndexError: list index out of range

Question

Problems with my code... when I execute it in Python and input a valid number, it comes up with "IndexError: list index out of range" even when its valid or invalid. I want it to print row[0] and row [1] if the number is between 0 & 9 else print out an error message.

import csv

number=input("Enter num: ")

with open("myfile.txt", "r") as file:
    fileReader = csv.reader(file)
    for row in fileReader:
        for i in range (0,10):
            if row[i] == number:
                print(row [0], row [1])
    else:
        print ("Error")

file.close()

Thanks in advance for any help!

What you asked for was to print row[0] and row[1] if the input value is between 0 and 9, but what you are doing is printing row[0] and row[1] if the input value matches a value stored in row between row[0] and row[9] . You also are assuming that row will contain 10 items (depending on your input, maybe this is an acceptable assumption, I don't know).

This will print row[0] and row[1] (for every row) if the input value is between 0 and 9. It assumes that each row contains at least two items.

import csv

number=input("Enter num: ")

if number >= 0 and number <= 9:
    with open("myfile.txt", "r") as file:
        fileReader = csv.reader(file)
        for row in fileReader:
            print(row [0], row [1])
else:
    print ("Error")

file.close()
