Example

fd = uio.open('/usr/test.py', mode='r', encoding='UTF-8')
fd.close()

uio.open(name, mode='r', **kwarg)

Opens a file. This is an alias for the built-in open() function.

Open Mode	Description
'r'	Open a file for reading.
'w'	Open a file for writing only. Overwrites the file if the file exists.
