[FIXED] Save the File path in a variable and later use it in a function

Issue

I am trying to have a function that takes in the recording file path as an input and converts it to a Pandas dataframe

Below is the code:

import pandas as pd
import numpy as np
from asammdf import MDF, Signal

def FileConverter(FilePath):
    DF01 = MDF(FilePath)
    DF01 = DF01.to_dataframe()
    return DF01

When I use the above code by providing the file path:

DF01 = FileConverter('C:\Users\hsr4ban\Desktop\Temp\DAT_to_DataFrame\Testing.dat')
print(DF01)

I get below error:

Input In [79]
    DF01 = FileConverter('C:\Users\hsr4ban\Desktop\Temp\DAT_to_DataFrame\Testing.dat')
                                                                                      ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

However, if same code is used as below by adding r'' or '\' in the beginnig of the path:

DF01 = FileConverter(r'C:\Users\hsr4ban\Desktop\Temp\DAT_to_DataFrame\Testing.dat')
DF01

or

DF01 = FileConverter('C:\\Users\hsr4ban\Desktop\Temp\DAT_to_DataFrame\Testing.dat')
DF01

The problem is solved.

But when we copy the file link from the computer, link appears as below: 'C:\Users\hsr4ban\Desktop\Temp\DAT_to_DataFrame\Testing.dat'

Wanted to know whether there is a way to paste only the link as copied from the computer and not get the error? I tried searching for some solutions online but still could not find a right solution.

Any suggestions will be really helpful.

Solution

Your task is not to belt Python for your way of thinking. Your task is change you way of thinking for better Python coding. So, first of all, tell me please—how (or from where) will you obtain the file path string?

>>> x = input('give me the path: ')
give me the path: C:\t\file_name.md5
>>> print(x)
'C:\\t\\file_name.md5'

Variant 2 - You will hard code it. So write R forward the 'C:\t\file_name.md5'

Variant 3 - Read from the file. You will read a list of lines like this:

['C:\\t\\file_name.md5\n']

So - stop hard coding Windows-path literals without forward R and you will be joyful.
