在python unicode错误unicodeescape中导入csv文件

Question

I am trying to work on a csv file in python

#code experiments
import csv
from statistics import mean
with open("C:\Users\xyr\zzz\kkkk\mmmm\ooooo\mpg.csv",'r') as csvfile:
    reader=list(csv.DictReader(csvfile))
    for item in reader:
        print (item)
        l=[item['cty']]
        new_list=list(map(float,l))
        res=(mean(new_list))
        print (res)

gives me the error

unicodeescape' codec can't decode bytes in position

However, if I am opening same file in an environment of anaconda's jupyter notebook I am able to open the file. This error is coming when I am using python IDLE environment what could be the reason for this error, how can I get rid of these in IDLE environment? I have tried using single quotes instead of double quotes but still the error remains.

Answer 1

The main reason you get an error is that \\u is an Unicode escape symbol. if symbols after that are not numeric - it raises an exception

Thy adding extra slashes in your path:

C:\\Users\\xxx\\...

or just use r prefix:

r'C:\Users...'
