# Pydoc:
|

|
|
# Open a file. The mode can be 'r', 'w' or 'a' for reading (default),
|
||
|
|
# | writing or appending. The file will be created if it doesn't exist
|
||
|
|
# | when opened for writing or appending; it will be truncated when
|
||
|
|
# | opened for writing. Add a 'b' to the mode for binary files.
|
||
|
|
# | Add a '+' to the mode to allow simultaneous reading and writing.
|
||
|
|
# | If the buffering argument is given, 0 means unbuffered, 1 means line
|
||
|
|
# | buffered, and larger numbers specify the buffer size. The preferred way
|
||
|
|
# | to open a file is with the builtin open() function.
|
||
|
|
# | Add a 'U' to mode to open the file for input with universal newline
|
||
|
|
# | support. Any line ending in the input file will be seen as a '\n'
|
||
|
|
# | in Python. Also, a file so opened gains the attribute 'newlines';
|
||
|
|
# | the value for this attribute is one of None (no newline read yet),
|
||
|
|
# | '\r', '\n', '\r\n' or a tuple containing all the newline types seen.
|
||
|
|
# |
|
||
|
|
# | 'U' cannot be combined with 'w' or '+' mode.
