Question

这是我用来向Jupyter笔记本读取csv文件的代码。

import pandas as pd

data = pd.read_csv("C:\\Users\\Mike\\Desktop\\File.csv")
for row in data:
    print(row)
    if len(data) > 5:
        break

我也尝试过

data = pd.read_csv(r"C:\Users\Mike\Desktop\File.csv")

这将导致以下错误

FileNotFoundError                         Traceback (most recent call last)
<ipython-input-7-332200c5442e> in <module>
      1 import pandas as pd
      2 
----> 3 data = pd.read_csv("C:\\Users\\Mike\\Desktop\\File.csv")
      4 for row in data:
      5     print(row)

FileNotFoundError: [Errno 2] File C:\Users\Mike\Desktop\File.csv does not exist: 'C:\\Users\\Mike\\Desktop\\File.csv'

尝试
后
导入操作系统

如果os.path.isfile（'C：\ Users \ Mike \ Desktop \ File.csv'）：打印（'文件存在'）其他： print（'文件不存在'）

如@LittinRajan所建议，我得到该文件不存在。好吧，显然该文件确实存在，并且我使用的是正确的路径，因此Jupyter可能有问题。感谢您的任何帮助，因为我是Python和Jupyter的新手
