File Not Found Error: Computer can't find an existing file

I'm trying to read a file in the same folder as my main.py and am getting the following error.

FileNotFoundError: [Errno 2] No such file or directory: 'central_park_census.csv'

Here is my code:

import pandas
all_data = pandas.read_csv("central_park_census.csv")
print(type(all_data))

The issue is that the said file exists and is in the same folder as my main.py. I use the windows OS and this error has been prevalent with text files also. Please help if you can :))
