Hướng dẫn pwd python

In Python, you can get and change (set) the current working directory with os.getcwd() and os.chdir().

The os module is included in the standard library, so no additional installation is required.

• os — Miscellaneous operating system interfaces — Python 3.7.4 documentation

This article describes the following contents.

• Get the current working directory: os.getcwd()
• Change the current working directory: os.chdir()

You can get the path of the current script file (.py) with __file__. See the following article.

• Get the path of current file (script) in Python: __file__

Get the current working directory: os.getcwd()

os.getcwd() returns the absolute path of the current working directory where Python is running as a string str.

getcwd stands for "get current working directory", and the Unix command pwd stands for "print working directory". Of course, you can print the current working directory with os.getcwd() and print().

import os

path = os.getcwd()

print(path)
# /Users/mbp/Documents/my-project/python-snippets/notebook

print(type(path))
# 

Use os.path to manipulate the path string. See the following article for details.

• Get the filename, directory, extension from a path string in Python

Change the current working directory: os.chdir()

You can change (set) the current working directory with os.chdir().

Specify the destination path in the argument. It can be absolute or relative. Use '../' to move up.

You can change the current directory like the Unix command cd. Both chdir and cd stand for "change directory".

os.chdir('../')

print(os.getcwd())
# /Users/mbp/Documents/my-project/python-snippets

With the __file__ and os.path functions, you can change the current directory to the directory where the running script file (.py) exists.

os.chdir(os.path.dirname(os.path.abspath(__file__)))

See the following article for details.

I hope someone can help as I am stuck, I can't find the answer to this problem anywhere on google.

I need to replace my forward slash path with a backslash path in order for it to work with windows command prompt. Forward slash paths work for local folders, i.e. C:/Users/Lorcan - but not network folders, i.e. //Networkfolder/Storage

I learned that you can't use the backslash in python as it is a special character, so you must use two backslashes. However, this causes my path to have too many backslashes, and command prompt doesn't work.

>>> s = '//Networkfolder/Storage/Myfolder/Myfile'
>>> s2 = s.replace('/','\\')
>>> s2
'\\\\Networkfolder\\Storage\\Myfolder\\Myfile'

I am working in python and I need to convert this:

C:\folderA\folderB to C:/folderA/folderB

I have three approaches:

dir = s.replace('\\','/')

dir = os.path.normpath(s) 

dir = os.path.normcase(s)

In each scenario the output has been

C:folderAfolderB

I'm not sure what I am doing wrong, any suggestions?

I recently found this and thought worth sharing:

import os

path = "C:\\temp\myFolder\example\\"
newPath = path.replace(os.sep, '/')
print(newPath)  # -> C:/temp/myFolder/example/

Your specific problem is the order and escaping of your replace arguments, should be

s.replace('\\', '/')

Then there's:

posixpath.join(*s.split('\\'))

Which on a *nix platform is equivalent to:

os.path.join(*s.split('\\'))

But don't rely on that on Windows because it will prefer the platform-specific separator. Also:

Note that on Windows, since there is a current directory for each drive, os.path.join("c:", "foo") represents a path relative to the current directory on drive C: (c:foo), not c:\foo.

Try

path = '/'.join(path.split('\\'))

Path names are formatted differently in Windows. the solution is simple, suppose you have a path string like this:

data_file = "/Users/username/Downloads/PMLSdata/series.csv"

simply you have to change it to this: (adding r front of the path)

data_file = r"/Users/username/Downloads/PMLSdata/series.csv"

The modifier r before the string tells Python that this is a raw string. In raw strings, the backslash is interpreted literally, not as an escape character.

Sorry for being late to the party, but I wonder no one has suggested the pathlib-library.

pathlib is a module for "Object-oriented filesystem paths"

To convert from windows-style (backslash)-paths to forward-slashes (as typically for Posix-Paths) you can do so in a very verbose (AND platform-independant) fashion with pathlib:

import pathlib

pathlib.PureWindowsPath(r"C:\folderA\folderB").as_posix()
>>> 'C:/folderA/folderB'

Be aware that the example uses the string-literal "r" (to avoid having "\" as escape-char) In other cases the path should be quoted properly (with double backslashes) "C:\\folderA\\folderB"

To define the path's variable you have to add r initially, then add the replace statement .replace('\\', '/') at the end.

for example:

In>>  path2 = r'C:\Users\User\Documents\Project\Em2Lph\'.replace('\\', '/')
In>>  path2 
Out>> 'C:/Users/User/Documents/Project/Em2Lph/'

This solution requires no additional libraries

How about :

import ntpath
import posixpath
.
.
.
dir = posixpath.join(*ntpath.split(s))
.
.

This can work also:

def slash_changer(directory):

if "\\" in directory:
    return directory.replace(os.sep, '/')
else:
    return directory

print(slash_changer(os.getcwd()))

this is the perfect solution put the letter 'r' before the string that you want to convert to avoid all special characters likes '\t' and '\f'... like the example below:

str= r"\test\hhd"

print("windows path:",str.replace("\\","\\\\"))
print("Linux path:",str.replace("\\","/"))

result:

windows path: \\test\\hhd
Linux path: /test/hhd

How do I enable backslash in Python?

In short, to match a literal backslash, one has to write '\\\\' as the RE string, because the regular expression must be "\\", and each backslash must be expressed as "\\" inside a regular Python string literal.

How do I change a backslash in Python?

We can use the replace() function to replace the backslashes in a string with another character. To replace all backslashes in a string, we can use the replace() function as shown in the following Python code.

Does Python use backslash or forward slash?

Programming languages, such as Python, treat a backslash (\) as an escape character. For instance, \n represents a line feed, and \t represents a tab. When specifying a path, a forward slash (/) can be used in place of a backslash. Two backslashes can be used instead of one to avoid a syntax error.

How do you change backward slash to forward slash?

By default the key is backslash, and is a way to refer to a backslash in a mapping, so by default these commands map \/ and \\ respectively. Press \/ to change every backslash to a forward slash, in the current line. Press \\ to change every forward slash to a backslash, in the current line.
