In Class Notes: FileIO

Reading Files

• Read the spam.txt file

with open('spam.txt') as f:
  contents = f.read()
  print(contents)

• NOTE: Using with will automatically close the file when the function is done executing

• help command
  • help(f) will provide information about the file provided by the file wrapper
• dir command
  • print(dir(f)) will return information about commands able to execute on the file
  • dir shows the attributes of the file
    • Attributes = the things we can do to the file

Writing Files

• Write to the spam.txt file

with open('spam.txt') as f:
  f.write('Do not like eggs')

• Can read non-text files by switching to binary reading
  • Example, a jpeg

  with open('brain.jpeg', mode='rb') as f:
    contents = f.read()
    print(contents)
  # Will print a string of bytes the refer to the jpeg
