Question

我只想将一个csv文件读入Pycharm，但是由于某种原因，它做得不好。

这是我的代码：

import csv
import os
import pandas as pd
path = '/Users/amy/Desktop/data_analysis/additionaldata/df1.csv'
df=pd.read_csv('path', sep=',')

返回错误

我也尝试过

import csv
import os
import pandas as pd
path = '/Users/amy/Desktop'
df=pd.read_csv("df1.csv")

也不起作用。

怎么了？我已经阅读了其他几篇文章，但仍然不确定如何执行此操作。任何帮助表示赞赏。谢谢

只需添加open()即可打开文件，然后再将其传递到pandas.read_csv()：

import pandas as pd
path = '/Users/amy/Desktop/data_analysis/additionaldata/df1.csv'
df = pd.read_csv(open(path), sep=',')

（注意：'path'只是一个值为'path'的字符串，如果您想使用实际的path，则不应该使用方括号。） < / p>

将csv文件读取到Pycharm中导致错误
