提问by user1774127
I have the following code in PyCharm
我在 PyCharm 中有以下代码
import pandas as pd
import numpy as np
import matplotlib as plt
df = pd.read_csv("c:/temp/datafile.txt", sep='\t')
df.head(10)
I get the following output:
我得到以下输出：
Process finished with exit code 0
I am supposed to get the first ten rows of my datafile, but these do not appear in PyCharm.
我应该得到我的数据文件的前十行，但这些没有出现在PyCharm.
I checked the Project interpreter and all settings seem to be alright there. The right packages are installed (numpy, pandas, matplotlib) under the right Python version.
我检查了项目解释器，所有设置似乎都没有问题。在正确的 Python 版本下安装了正确的包（numpy、pandas、matplotlib）。
What am I doing wrong? Thanks.
我究竟做错了什么？谢谢。

PyCharmis not Python Shellwhich automatically prints all results. You have to use print()to display anything.
PyCharm不是Python Shell自动打印所有结果。你必须使用print()来显示任何东西。
print(df.head(10))

For printing all data
用于打印所有数据
print(df)
打印（df）
By Default it will print top 5 records for head.
默认情况下，它将打印头部的前 5 条记录。
print(df.head())
打印（df.head（））
If you need 10 rows then you can write this way
如果你需要 10 行，那么你可以这样写
print(df.head(10))
打印（df.head（10））
