Dataframe head not shown in PyCharm

问题:

I have the following code in PyCharm

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:

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.

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.

What am I doing wrong? Thanks.

回答1:

PyCharm is not Python Shell which automatically prints all results. You have to use print() to display anything.

print(df.head(10))

回答2:

For printing all data

print(df)

By Default it will print top 5 records for head.

print(df.head())

If you need 10 rows then you can write this way

print(df.head(10))

I did File-Invalidate Caches/Restart Option Invalidate and after that I was able to get the head:
