8.2 os.path--Common path name operation (1)

Os.path.isabs (PATH)

Returns True if the parameter path is an absolute path , otherwise Falseis returned.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Isabs (PATHSTR)

Print (R)

The resulting output is as follows:

True

Os.path.isfile (PATH)

Returns True if the parameter path is a file return , otherwise False.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Isfile (PATHSTR)

Print (R)

The resulting output is as follows:

True

Os.path.isdir (PATH)

Returns True if the parameter path is a directory , otherwise False.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Isdir (PATHSTR)

Print (R)

The resulting output is as follows:

False

Os.path.islink (PATH)

Returns True if the parameter path is a symbol entry connection, otherwise False.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Islink (PATHSTR)

Print (R)

The resulting output is as follows:

False

Os.path.ismount (PATH)

Determines if the path parameter is a mount point, if True is returned .

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Ismount (PATHSTR)

Print (R)

The resulting output is as follows:

False

Os.path.join (path1[, path2[, ...])

Properly connect directories and file composition paths.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Join (' f:\\temp ', ' \\py\\cal_1.py ')

Print (R)

The resulting output is as follows:

F:\py\cal_1.py

Os.path.normcase (PATH)

Formats the path 's case and slash.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Normcase (PATHSTR)

Print (R)

The resulting output is as follows:

f:\temp\py\cal_1.py

Os.path.normpath (PATH)

Remove the relative path from the path.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\. \\py\\cal_1.py '

R = Normpath (PATHSTR)

Print (R)

The resulting output is as follows:

F:\py\cal_1.py

Os.path.realpath (PATH)

Returns the actual path, if the relative path is removed, if the shortcut returns the True path.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\. \\py\\cal_1.py '

R = Realpath (PATHSTR)

Print (R)

The resulting output is as follows:

F:\py\cal_1.py

Os.path.relpath (Path, Start=os.curdir)

Converts the path to a relative path with the directory start as the standard.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\. \\py\\cal_1.py '

R = RelPath (PATHSTR)

Print (R)

The resulting output is as follows:

.. \.. \.. \py\cal_1.py

Os.path.samefile (path1, path2)

Determine if two paths are the same. Returns Falseif the same returns True.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = RelPath (PATHSTR)

Print (R)

R = Samefile (Pathstr, R)

Print (R)

The resulting output is as follows:

.. \.. \py\cal_1.py

True

Os.path.sameopenfile (FP1, FP2)

Determine if FP1 and FP2 are the same file, if the same returns True, otherwise Falseis returned.

Example:

#python 3.4

From Os.path Import *

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = RelPath (PATHSTR)

Print (R)

FP1 = open (PATHSTR)

FP2 = open (R)

R = Sameopenfile (Fp1.fileno (), Fp2.fileno ())

Print (R)

Fp1.close ()

Fp2.close ()

The resulting output is as follows:

.. \.. \py\cal_1.py

True

Os.path.samestat (STAT1, STAT2)

The file status is determined to determine whether two files point to the same file, and if true, returns False.

Example:

#python 3.4

From Os.path Import *

Import OS

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = RelPath (PATHSTR)

Print (R)

FP1 = Os.stat (PATHSTR)

FP2 = Os.stat (r)

R = Samestat (FP1, FP2)

Print (R)

The resulting output is as follows:

.. \.. \py\cal_1.py

True

Os.path.split (PATH)

The path is divided into two parts: path and file name.

Example:

#python 3.4

From Os.path Import *

Import OS

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Split (PATHSTR)

Print (R)

The resulting output is as follows:

(' F:\\temp\\py ', ' cal_1.py ')

Os.path.splitdrive (PATH)

The path paths are decomposed into drive and relative to drive paths.

Example:

#python 3.4

From Os.path Import *

Import OS

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Split (PATHSTR)

Print (R)

R = splitdrive (PATHSTR)

Print (R)

The resulting output is as follows:

(' F:\\temp\\py ', ' cal_1.py ')

(' F: ', ' \\Temp\\py\\cal_1.py ')

Os.path.splitext (PATH)

The path paths are decomposed into file names and suffixes.

Example:

#python 3.4

From Os.path Import *

Import OS

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Split (PATHSTR)

Print (R)

R = splitdrive (PATHSTR)

Print (R)

R = Splitext (PATHSTR)

Print (R)

The resulting output is as follows:

(' F:\\temp\\py ', ' cal_1.py ')

(' F: ', ' \\Temp\\py\\cal_1.py ')

(' F:\\temp\\py\\cal_1 ', '. Py ')

Os.path.splitunc (PATH)

The path is decomposed as a UNC way.

Example:

#python 3.4

From Os.path Import *

Import OS

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Split (PATHSTR)

Print (R)

R = splitdrive (PATHSTR)

Print (R)

R = Splitext (PATHSTR)

Print (R)

R = Splitunc (PATHSTR)

Print (R)

R = Splitunc (R ' \\192.168.0.1\abc\test.py ')

Print (R)

The resulting output is as follows:

(' F:\\temp\\py ', ' cal_1.py ')

(' F: ', ' \\Temp\\py\\cal_1.py ')

(' F:\\temp\\py\\cal_1 ', '. Py ')

(', ' f:\\temp\\py\\cal_1.py ')

(' \\\\192.168.0.1\\abc ', ' \\test.py ')

Os.path.supports_unicode_filenames

Returns Trueif the Unicode string can be a file name ,otherwise False.

Example:

#python 3.4

From Os.path Import *

Import OS

Pathstr = ' f:\\temp\\py\\cal_1.py '

R = Split (PATHSTR)

Print (R)

Print (Supports_unicode_filenames)

The resulting output is as follows:

(' F:\\temp\\py ', ' cal_1.py ')

True
