| 10 | lib/python<version>/site-packages as well as lib/site-python. |
| 11 | On other platforms (such as Windows), it tries each of the |
| 12 | prefixes directly, as well as with lib/site-packages appended. The |

| 21 | the key "include-system-site-packages" set to anything other than "false" |

Guido van Rossum | f30bec7 | 1997-08-29 22:30:45 +0000 | [diff] [blame] | 29 | A path configuration file is a file whose name has the form |
| 30 | <package>.pth; its contents are additional directories (one per line) |

| 33 | sys.path more than once. Blank lines and lines beginning with |
Guido van Rossum | facf24b | 2001-12-17 16:07:06 +0000 | [diff] [blame] | 34 | '#' are skipped. Lines starting with 'import' are executed. |

Guido van Rossum | f30bec7 | 1997-08-29 22:30:45 +0000 | [diff] [blame] | 36 | For example, suppose sys.prefix and sys.exec_prefix are set to |
Thomas Wouters | 00ee7ba | 2006-08-21 19:07:27 +0000 | [diff] [blame] | 37 | /usr/local and there is a directory /usr/local/lib/python2.5/site-packages |
Guido van Rossum | 62b297b | 1997-09-08 02:14:09 +0000 | [diff] [blame] | 38 | with three subdirectories, foo, bar and spam, and two path |
| 39 | configuration files, foo.pth and bar.pth. Assume foo.pth contains the |

| 42 | # foo package configuration |

| 44 | bar |
| 45 | bletch |

| 47 | and bar.pth contains: |
| 48 | |
| 49 | # bar package configuration |
| 50 | bar |
| 51 | |
| 52 | Then the following directories are added to sys.path, in this order: |
| 53 | |
Thomas Wouters | 00ee7ba | 2006-08-21 19:07:27 +0000 | [diff] [blame] | 54 | /usr/local/lib/python2.5/site-packages/bar |

Guido van Rossum | f30bec7 | 1997-08-29 22:30:45 +0000 | [diff] [blame] | 56 | |
| 57 | Note that bletch is omitted because it doesn't exist; bar precedes foo |
| 58 | because bar.pth comes alphabetically before foo.pth; and spam is |
| 59 | omitted because it is not mentioned in either path configuration file. |
