(unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \

[Jack_Sparrow]

HI there,
I have follow problem:

import pandas as pd

subway_df = pd.read_csv('C:\Users\DSule\Desktop\python\nyc.csv')

 File "<ipython-input-25-80cb9d4c408e>", line 3
    subway_df = pd.read_csv('C:\Users\DSule\Desktop\python\nyc.csv')
                           ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

I tried to solve this problem with three different solutions:
- \\
- r
- "nyc.csv"

But nothing works for me...
I know, there are already similiar questions in this forum. But if you take a closer look to this questions, they are not answered
Feel frustraited

I use Python 3
And I installed Jupyter with anaconda

Never use use single backslash (\) that way in path,because of escape character.
\U starts an eight-character Unicode escape in Python 3.

Error:
>>> s = 'C:\Users\DSule\Desktop\python\nyc.csv'
Traceback (most recent call last):
.........
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

Here are three ways that work.

>>> # Raw string(r)
>>> s = r'C:\Users\DSule\Desktop\python\nyc.csv'
>>> s
'C:\\Users\\DSule\\Desktop\\python\\nyc.csv'

>>> # Other way /
>>> s = 'C:/User/DSule/Desktop/python/nyc.csv'
>>> s
'C:/User/DSule/Desktop/python/nyc.csv'

>>> # Double up
>>> s = 'C:\\Users\\DSule\\Desktop\\python\\nyc.csv'
>>> s
'C:\\Users\\DSule\\Desktop\\python\\nyc.csv'

Thank you!
I tried all of them. Here are results:

#Input1: 
import pandas as pd
subway_df = pd.read_csv(r'C:\Users\DSule\Desktop\python\nyc.csv')
#Output1
NO output/No reaction

#Input2
import pandas as pd
subway_df = pd.read_csv('C:/User/DSule/Desktop/python/nyc.csv')
#Output2
File b'C:/User/DSule/Desktop/python/nyc.csv' does not exist

#Input 3
import pandas as pd
subway_df = pd.read_csv('C:\\Users\\DSule\\Desktop\\python\\nyc.csv')
#Output 3
NO output/No reaction

Any other ideas?

Check your path Path and file.

Here a little basic about Path and file as i think you struggle with that.
Navigate training in cmd and check file,this way you now that path is correct.
Then open file Pandas.
cmd:

Microsoft Windows [Version 10.0.16299.431]
(c) 2017 Microsoft Corporation. Med enerett.

# Navigate with cd
C:\Windows\System32>cd\
C:\>cd foo1

# look at files in folder
C:\foo1>dir
 Volume in drive C has no label.
 Volume Serial Number is EED7-45CC

 Directory of C:\foo1

11.05.2018  12:46    <DIR>          .
11.05.2018  12:46    <DIR>          ..
13.09.2017  22:03                 0 cd1.txt
11.05.2018  12:40                73 my_csv.csv
               2 File(s)             73 bytes
               2 Dir(s)  66 910 232 576 bytes free

# Open file in folder
C:\foo1>type my_csv.csv
Student,Age,Subject
Adam,13,Maths
Alex,14,English
Shawn,15,Geography

cmd Anaconda:

G:\Anaconda3>python
Python 3.6.5 |Anaconda custom (64-bit)| (default, Mar 29 2018, 13:32:41) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
>>>
>>> df = pd.read_csv(r'C:\foo1\my_csv.csv')
>>> df
  Student  Age    Subject
0    Adam   13      Maths
1    Alex   14    English
2   Shawn   15  Geography
>>>

Then it also work the same in Jupyter NoteBook.

Yes, you're right! there is smth wrong with the path. I'll take a closer look at it.

Hi Jack_Sparrow. i did not see your resolution to this issue. I followed all the steps noted above including r, \\, /
none worked similar to you.
then i used cmd to verify the path and the file. there were no issues as i was able to locate and open the file with cmd.
used that path in Jupyter and still get Syntax Error.
Can you provide any additional assistance or thought on this?
