Python 熊猫头功能的输出不显示

我正在做一个

pandas

培训，在第二个实验室，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”，但它没有打印

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()

您还必须打印df.head（）

刚刚注意到代码在CLI中运行正常。问题在于执行lab2.py时。如果在jupter notebook上执行，它会将输出显示为html内容。但在IDE上，为了在控制台上显示，您需要使用print。今天遇到了这个问题。“来自SQL”的熊猫入门文档假定您正在使用笔记本。我在输出中什么也看不到，因为我只是在制作脚本。我还没用笔记本呢。

print(df.head())
