importing Text files

import textfiles

# Open a file: file
file = open('opa.txt','r')

# Print it
print(file.read())

# Check whether file is closed
print(file.closed)

# Close file
file.close()

# Check whether file is closed
print(file.closed)

context manager

it is important to close an open file. a way to do this automaticaly is to use a context manager. Out of the context everything will be automatically closed.

you can bind a variable file by using a context manager construct:

with open('huck_finn.txt') as file:

with open('huck_finn.txt') as file:
    print(file.read())
