FileNotFoundError: [Errno 2] No such file or directory: 'codedata.pkl'-CodePudding

This is a school program to learn how to use file and directory in Python. So to do my best I create a function to open, set it as a variable and close properly my file.

But I got the error of the title:

FileNotFoundError: [Errno 2] No such file or directory: 'codedata.pkl'

def load_db():
""" load data base properly 
And get ready for later use

Return:
-------
    cd : (list) list of tuples
"""

file = open('codedata.pkl', 'rb')
codedata = pickle.loads(file)
file.close()

return codedata

From the interpreter, this is the line

file = open('codedata.pkl', 'rb')

Which is the problem, but I don't see where is the source of the problem.

Can anyone help me?

CodePudding user response：

Can you check what is the location of the file?

If your file is located at /Users/abc/Desktop/, then the code to open the file on python would be as shown below

file = open('/Users/abc/Desktop/codedata.pkl', 'rb')
codedata = pickle.load(file)
file.close()

You can also check if the file exists at the desired path by doing something like this

import os
filepath = '/Users/abc/Desktop/codedata.pkl'
if os.path.exists(filepath):
    file = open('/Users/abc/Desktop/codedata.pkl', 'rb')
    codedata = pickle.load(file)
    file.close()
else:
    print("File not present at desired location")
