How to Fix the 'unicode error' when Reading CSV Files in Python?

Troubleshooting "Unicode Error" While Reading CSV Files in Python

Users attempting to read CSV files using Python may encounter an error stating "(unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated UXXXXXXXX escape."

Cause:

This error occurs when a raw string containing Unicode escape sequences is used as the path to the CSV file. Without the raw string prefix (r), the backslashes () in the file path are interpreted as escape characters, causing the error.

Fixes:

To resolve this issue, one of the following solutions can be employed:

1. Raw String Prefix: Precede the file path with the raw string prefix (r), which prevents the backslashes from being interpreted as escape characters.

   data = open(r"C:\Users\miche\Documents\school\jaar2\MIK.6\vektis_agb_zorgverlener")

2. Forward Slashes: Use forward slashes (/) instead of backslashes in the file path. This effectively removes the need for escape characters.

   data = open("C:/Users/miche/Documents/school/jaar2/MIK/2.6/vektis_agb_zorgverlener")

3. Double Backslashes: Escape the backslashes in the file path by doubling them, allowing them to be interpreted as literal characters.

   data = open("C:\Users\miche\Documents\school\jaar2\MIK\2.6\vektis_agb_zorgverlener")
