不显示pandas head函数的输出

Question

我正在pandas接受培训，在第二个实验室中，我应该打开一个文件并打印前 5 行。问题是，从下面的代码中，我只打印了“完成”，但没有打印df.head(). 我找不到原因。有小费吗？

import pandas as pd

filename="https://archive.ics.uci.edu/ml/machine-learning- 
databases/autos/imports-85.data"

hs = ["symboling","normalized-losses","make","fuel-type","aspiration", 
   "num-of-doors","body-style", "drive-wheels","engine-location","wheel-base", "length","width","height","curb-weight","engine-type", "num-of-cylinders", "engine-size","fuel-system","bore","stroke","compression-ratio","horsepower",
     "peak-rpm","city-mpg","highway-mpg","price"]

df = pd.read_csv(filename, names=hs)
print("Done")
df.head()

Answer 1

你也必须打印 df.head() 。

print(df.head())
