path = r'C:\Program Files\1\1.exe'
I can run a program using the path above. I don't want to hardcode it, so I'm trying to use a variable in place of the 1s. This is what I came up with:
variable1 = '1'
path = r'C:\Program Files\ , +variable1 , +\, +variable1, +.exe'
This doesn't work. How do I make it work?


variable1 = '1'
path = 'C:\\Program Files\\'+variable1+'\\'+variable1+'.exe'
\ is special char so you need to escape it with another \

Adding a absolute path that has a \f in it [duplicate]

How can I put an actual backslash in a string literal (not use it for an escape sequence)?

While adding an absolute path to my script because it has a \f in it the code won't run properly.
C:\Users\showoi\Desktop\website\repository\fileAdder\softwarelisting.xlsx
The file is in the same directory as the script but using a relative path won't work. No misspellings or anything.

Use python r string
path=r'C:\Users\showoi\Desktop\website\repository\fileAdder\softwarelisting.xlsx'

Use one of the following ways:
r"C:\Users\showoi\Desktop\website\repository\fileAdder\softwarelisting.xlsx"
"C:\\Users\\showoi\\Desktop\\website\\repository\\fileAdder\\softwarelisting.xlsx"
"C:/Users/showoi/Desktop/website/repository/fileAdder/softwarelisting.xlsx

Changing `\` to `/` [duplicate]

Python replace / with \

Closed 8 months ago.
I would like to go the opposite direction of the post Python replace / with \.
For example, the path to desktop:
import os
desktop = os.path.join(os.path.join(os.environ['USERPROFILE']), 'Desktop')
print(desktop)
The above code prints "C:\Users\r2d2w\Desktop". I would like to convert it to "C:/Users/r2d2w/Desktop". How can this be done? The line desktop.replace("\", "/") will not work and will give error "EOL while scanning string literal".

Have you already tried to do:
desktop.replace("\\", "/")
?

I am new in the regular expression and trying to extract the file name from a string which is basically a file path.
string = "input_new/survey/argentina-attributes.csv"
string_required = argentina-attributes
i know i can do this by below code.
string.split('/')[2].split('.')[0]
but I am looking to do this by using regular expression so if in future the formate of the path changes(input_new/survey/path/path/argentina-attributes.csv) should not affect the output.
i know kind of similar question asked before but I am looking for a pattern which will work for my use case.

Try this,
>>> import re
>>> string = "input_new/survey/argentina-attributes.csv"
Output:
>>> re.findall(r'[^\/]+(?=\.)',string) # or re.findall(r'([^\/]+)\.',string)
['argentina-attributes']
Referred from here

Try this:
string = "input_new/survey/argentina-attributes.csv"
new_string = string.split('/')[-1].split('.')[0]
print(new_string)

How can I do that in the shortest way?

folders = Path.split('\')
It will return you the required list of the folders

I am very new to Python and am getting this small problem. I am using Python 3.3
There is a variable I declared in my code
file_name = "resource\email\ham\6.txt"
However, when I look for the variable, it appends additional numbers
>>file_name
'resource\\email\\ham\x06.txt'
Is there a reason why it behaves as so? If not, how do I remove those additional characters? Also, why are they there?

Use r raw string:
file_name = r"resource\email\ham\6.txt"
Double \:
file_name = "resource\\email\\ham\\6.txt"
Or /:
file_name = "resource/email/ham/6.txt"
\ has a special meaning in python, it is used to escape characters.
