pandas 头函数的输出不显示

Output of pandas head function is not displayed

我正在进行 pandas 培训,在第二个实验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 "Done",但没有打印 df.head() 的输出。我找不到原因。 ¿有什么建议吗?

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()

您必须将 df.head() 打印到。

print(df.head())
