# How to Fix the IO Error in Python

Here is [how to fix](https://srinimf.com/2015/08/23/mainframe-tip-resolution-for-member-in-use-error/) IO errors (ValueError: I/O operation on closed file.) in Python. I analyzed the root of it and fixed the issue. Here my topic is what is the program? What is the IO error? How did I fix it?

The program’s logic is to get user input and write**[it into a CSV file](https://srinimf.com/2022/07/06/how-to-handle-csv-files-in-python/)**. While writing I got an error.

## What is the program

```
import csv
with open("mycsvfile1.csv","w") as myfile1:
    mywrite=csv.writer(myfile1) # CS1
    print(type(mywrite)) # CS2
while True:    
        myroll_no=input("Enter Student Roll No:") # CS4
        myname=input("Enter Student Name:") # CS5
        myage=input("Enter Student Age:") # CS6
        mycontactno=input("Enter Student contact number:") # CS7
        print(myfile1.closed)
        mywrite.writerow([myroll_no, myname, myage, mycontactno]) # CS8
        check = input("Do you want to enter one more student data: (Yes|No): ") # CS9
        if check.upper() == 'NO': # CS10
            break
print("Total Students data written to csv file successfully")
```

## What is the IO error?

The program was not successful and displayed an IO error.

```
<class '_csv.writer'>
Enter Student Roll No:
10
Enter Student Name:
Ravi
Enter Student Age:
23
Enter Student contact number:
112233445
True
Traceback (most recent call last):
  File "main.py", line 13, in <module>
    mywrite.writerow([myroll_no, myname, myage, mycontactno]) # CS8
ValueError: I/O operation on closed file.
** Process exited - Return Code: 1 **
Press Enter to exit terminal
```

## How did I fix the error?

The code **“while true break loop**” is in the wrong place, which means it is **outside the loop.** So I have corrected the code. T

```
import csv
with open("mycsvfile1.csv","w") as myfile1:
    mywrite=csv.writer(myfile1) # CS1
    print(type(mywrite)) # CS2
    while True:    
        myroll_no=input("Enter Student Roll No:") # CS4
        myname=input("Enter Student Name:") # CS5
        myage=input("Enter Student Age:") # CS6
        mycontactno=input("Enter Student contact number:") # CS7
        print(myfile1.closed)
        mywrite.writerow([myroll_no, myname, myage, mycontactno]) # CS8
        check = input("Do you want to enter one more student data: (Yes|No): ") # CS9
        if check.upper() == 'NO': # CS10
            break
    print("Total Students data written to csv file successfully")
```

The reason for the IO error is “**while true break loop**” is coded outside the loop. So the opened CSV file closes automatically by the python compiler. Due to this, while writing, it displays” ValueError: I/O operation on closed file.”.
