Unicode Error unicodeescape codec can t decode bytes Cannot open text files in Python 3

Question

I am using Python 3 1 on a Windows 7 machine  Russian is the default system language  and utf-8 is the default encoding  Looking at the answer to a previous question  I have attempting using the  quot codecs quot  module to give me a little luck  Here s a few examples   gt  gt  gt  g   codecs open  quot C  Users Eric Desktop beeline txt quot    quot r quot   encoding  quot utf-8 quot   SyntaxError   unicode error   unicodeescape  codec can t decode bytes in position 2-4  truncated  UXXXXXXXX escape   lt pyshell 39 gt   line 1    gt  gt  gt  g   codecs open  quot C  Users Eric Desktop Site txt quot    quot r quot   encoding  quot utf-8 quot   SyntaxError   unicode error   unicodeescape  codec can t decode bytes in position 2-4  truncated  UXXXXXXXX escape   lt pyshell 40 gt   line 1    gt  gt  gt  g   codecs open  quot C  Python31 Notes txt quot    quot r quot   encoding  quot utf-8 quot   SyntaxError   unicode error   unicodeescape  codec can t decode bytes in position 11-12  malformed  N character escape   lt pyshell 41 gt   line 1    gt  gt  gt  g   codecs open  quot C  Users Eric Desktop Site txt quot    quot r quot   encoding  quot utf-8 quot   SyntaxError   unicode error   unicodeescape  codec can t decode bytes in position 2-4  truncated  UXXXXXXXX escape   lt pyshell 44 gt   line 1   My last idea was  I thought it might have been the fact that Windows  quot translates quot  a few folders  such as the  quot users quot  folder  into Russian  though typing  quot users quot  is still the correct path   so I tried it in the Python31 folder  Still  no luck  Any ideas

The problem is with the string   C  Users Eric Desktop beeline txt    Here   U in  C  Users    starts an eight-character Unicode escape  such as  U00014321  In your code  the escape is followed by the character  s   which is invalid   You either need to duplicate all backslashes    C   Users  Eric  Desktop  beeline txt    Or prefix the string with r  to produce a raw string    r C  Users Eric Desktop beeline txt

path   pd read csv    C  Users mravi Desktop filename       The error is because of the path that is mentioned   Add  r  before the path   path   pd read csv   r C  Users mravi Desktop filename       This would work fine

With Python 3 I had this problem    self path    T  PythonScripts Projects Utilities    produced this error    self path    T  PythonScripts Projects Utilities                 SyntaxError   unicode error   unicodeescape  codec can t decode bytes in  position 25-26  truncated  UXXXXXXXX escape   the fix that worked is    self path   r T  PythonScripts Projects Utilities    It seems the   U  was producing an error and the  r  preceding the string turns off the eight-character Unicode escape  for a raw string  which was failing   This is a bit of an over-simplification  but it works if you don t care about unicode   Hope this helps someone

Typical error on Windows because the default user directory is C  user  lt your user gt   so when you want to use this path as an string parameter into a Python function  you get a Unicode error  just because the  u is a Unicode escape  Any character not numeric after this produces an error   To solve it  just double the backslashes  C   user   lt  your user gt

Prefixing with  r  works very well  but it needs to be in the correct syntax  For example   passwordFile   open r   C  Users Bob SecretPasswordFile txt       No need for    here - maintains readability and works well
