#Python 导入数据——分析师项目Alex

Question

我正在研究 Python/数据分析组合，正在观看 Alex the Analyst youtube 视频。 (https://www.youtube.com/watch?v=ocdwh0KYeUs&list=PLUaB-1hjhk8H48Pj32z4GZgGWyylqv85f&index=5)

但是，他提供的代码并不能正常工作。 我尝试了此代码 $ export XDG_RUNTIME_DIR=""（位于：Jupyter notebook permission error），但这也不起作用。

import pandas as pd 
import numpy as np 
import seaborn as sns 
import matplotlib.pyplot as plt 
import matplotlib.mlab as mlab 
import matplotlib 
plt.style.use('ggplot') 
from matplotlib.pyplot import figure 
%matplotlib inline 
matplotlib.rcParams['figure.figsize'] = (12,8) 
pd.options.mode.chained_assignment = None 
df = pd.read_csv(r'C:\Users\enana\Downloads\movies.csv')

我在做这个项目时只是想跟着做，所以我不太明白上面发生了什么。当我返回如下代码时，我不知道发生了什么：

请帮忙。

请尝试以下方法：在处理此类问题时，我们需要了解我们提供的路径应该是双“\”。

df = pd.read_csv(r"C:\\Users\\enana\\Downloads\\movies.csv")

您的问题可能会得到解决。
