Fred Drake | 4f31694 | 1998-04-27 14:54:06 +0000 | [diff] [blame] | 8 | This module defines the class \class{FTP} and a few related items. |
Fred Drake | 5967667 | 1999-03-18 16:08:54 +0000 | [diff] [blame] | 9 | The \class{FTP} class implements the client side of the FTP |
| 10 | protocol.\indexii{FTP}{protocol} You can use this to write Python |
| 11 | programs that perform a variety of automated FTP jobs, such as |
| 12 | mirroring other ftp servers. It is also used by the module |
| 13 | \refmodule{urllib} to handle URLs that use FTP. For more information |
| 14 | on FTP (File Transfer Protocol), see Internet \rfc{959}. |

Guido van Rossum | cca8d2b | 1995-03-22 15:48:46 +0000 | [diff] [blame] | 85 | Set the instance's debugging level. This controls the amount of |
Fred Drake | 6a1eefe | 1998-03-12 06:04:53 +0000 | [diff] [blame] | 86 | debugging output printed. The default, \code{0}, produces no |
| 87 | debugging output. A value of \code{1} produces a moderate amount of |
| 88 | debugging output, generally a single line per request. A value of |
| 89 | \code{2} or higher produces the maximum amount of debugging output, |
| 90 | logging each line sent and received on the control connection. |
