writelines¶

Description¶

Writes a sequence of strings to the file.

Syntax¶

file. writelines(iterable)

sequence: Any iterable object producing strings, typically a list of strings.

Remarks¶

There is no return value. (The name is intended to match readlines(); writelines() does not add line separators.) Files support the iterator protocol. Each iteration returns the same result as readline(), and iteration ends when the readline() method returns an empty string.

File objects also offer a number of other interesting attributes. These are not required for file-like objects, but should be implemented if they make sense for the particular object.

Return Value¶

None

Time Complexity¶

#TODO

Example¶

>>> f = open(r'C:\test.txt', 'w')
>>> f.writelines(['foo', 'bar'])
>>> f.close()
>>> f = open(r'C:\test.txt')
>>> f.read()
'foobar'
