What are the modes a file can be opened using Python?
Files in python can be opened in the following modes.
|'r'||Read mode. (default)|
|'w'||Write mode. Creates a new file if it does not exist or truncates the file if it exists.|
|'x'||Open a file for exclusive creation. If the file already exists, the operation fails.|
|'a' ||Appending at the end of the file without truncating it. Creates a new file if it does not exist.|
|'t'||Open in text mode. (default)|
|'b'||Open in binary mode.|
|'+' ||Open a file for updating (reading and writing)|
These modes can be used in combinations and need to be passed as the second argument when opening a file. If you don't specify a mode, files are opened in readonly text mode.
f = open("test.txt") # Equivalent to rt or race f = open("test.txt", 'w') # Write in text mode f = open("test.bmp", 'r+b') # Read/write in binary mode f = open("test.txt", 'a') # Append mode
