为什么字符串不会拆分为使用 python 从 csv 读取

Question

Input config_note.csv:

Default,case 1,case 2,Time: \nJoin Connection: \nUser Remark:

I then only extract the last column by following command:

col_list = ["project", "name 1", "name 2", "note"]
df = pd.read_csv("config_note.csv", usecols=col_list, engine='python',error_bad_lines=False)
print('df["note"]:', str(df["note"].iloc[0]))

But the output remains as:

Time: \nJoin Connection: \nUser Remark:

I've tried to input variable directly and get what I want:

 test = "Time: \nJoin Connection: \nUser Remark:"
 print(test)

This is what I want:

Time:
Join Connection: 
User Remark:

Could anyone please help me with the input issue from csv?

Answer 1

The problem is the string is encoded as a raw string, you can print it out into a normal string with

print(df["note"].iloc[0].encode().decode('unicode-escape'))

so you can create a function:

def decode(x):
    return x.encode().decode('unicode-escape')
print(decode(df["note"].iloc[0]))
