I wrote a program, and when I run it in Visual Studio Code it gives an error but not when I run it in the Python IDLE. I have set up the environment variable but it still doesn't work. So can u please tell me how to fix this

This also has happened when I import a file and all sorts of places where I want to use a different file

This is my compiler.py file

fileName = "file.txt"

file = open("file.txt", "r+")

def file_len(fname):
 with open(fname) as f:
 for i, l in enumerate(f):
 pass
 return i + 1

for loop in range(file_len(fileName) + 1) :
 print(loop)

and this is my file.txt

hallo

When I run this in Visual Studio Code it gives this error

PS C:UsersHarry KrugerDocumentscode> & "C:/Program Files (x86)/Python37-32/python.exe" "c:/Users/Harry Kruger/Documents/code/quicks/compiler.py"

Traceback (most recent call last):
 File "c:/Users/Harry Kruger/Documents/code/quicks/compiler.py", line 4, in <module>
 file = open("file.txt", "r+")
FileNotFoundError: [Errno 2] No such file or directory: 'file.txt'

And when i run ir in python IDLE it works and the output is this

I guess that you run python IDLE in the directory "c:/Users/Harry Kruger/Documents/code/quicks. Therefore your code will pass because in this directory is (probably?) also the file.txt.

However in VS Code you seem to run python in the directory C:UsersHarry KrugerDocumentscode where the file.txt is not present and therefore your code fails.

To fix this and run your code in VS Code you have two options:

1. In VS Code powershell navigate to the directory that contains the file.txt. In your case you should be able to do it by entering cd "c:/Users/Harry Kruger/Documents/code/quicks" and then call your code.


2. You can modify your code to use the absolute path of the file. Then you can invoke it from any directory. To do so you have to modify the with open() statement. Replace it with:
   
   

   from os import path
   with open(path.join(path.abspath(path.dirname(__file__)), 'file.txt'), 'r+') as f:
   

   
   
   this snipet will look for the absoulte path of the file and open it.
