NameError: name 'u' is not defined [closed]-CodePudding

#col_names = ['user_id', 'item_id', 'rating', 'timestamp']
data = pd.read_table(u.data, names=['user_id', 'item_id', 'rating', 'timestamp'])
data = data.drop('timestamp', axis=1)
data.info()

I ran the code above to read a file named 'u.data'. However, I am receiving the error below. Please help me how could I solve it.

CodePudding user response：

'u.data' is string ?

data = pd.read_table('u.data', names=['user_id', 'item_id', 'rating', 'timestamp'])

CodePudding user response：

You should give the file name as a string like "C://u.data"
