read a file in python

To read a file in Python, you can use the open() function with the mode argument set to 'r'. This will open the file in read mode, allowing you to read the contents of the file.

main.py
# Open the file in read mode
file = open('filename.txt', 'r')

# Read the contents of the file
contents = file.read()

# Close the file
file.close()

Alternatively, you can use a with statement to automatically close the file after you are done reading its contents.

main.py
# Open the file with a with statement
with open('filename.txt', 'r') as file:
    # Read the contents of the file
    contents = file.read()

# The file is automatically closed after the with block is exited

Once you have read the contents of the file, you can manipulate it as needed for your program.
