write()
Here’s how to use write() function.
f. write()
Description:
Write a string or a sequence into a file.
Syntax:
|
f.write(s) |
|
|
f.write(A) |
Write A, the sequence of strings to file f; each member occupies one row |

Parameter:
|
s |
A string |
|
f |
A file |
|
A |

@a |
Append data into a file, instead of overwriting it. If the file has contents before appending, then start a new line (with carriage return) to append |
|
@b |
Write as a binary file without using the carriage return automatically |
|
@w |
Use Windows-style \r\n line break; by default, the line break is specified by OS |
Example:
