python pandas dataframe head() displays nothing

Question

I am new to using pandas and I just don't know what to do with this :

I am using python. I have (properly) installed anaconda. In my file I simply create a DataFrame (first by importing it from read_csv, then recreating it by hand to make sure that was not the problem). When I do print (dataframe) it prints:

        km |  price 0  | 240000 |  3650  [...]  23  | 61789 |  8290 

When I do dataframe.info() I get this :

class 'pandas.core.frame.DataFrame'  Int64Index: 24 entries, 0 to 23  Data columns (total 2 columns):  km       24 non-null int64  price    24 non-null int64  dtypes: int64(2)  memory usage: 576.0 bytes 

Which is perfect. But any other simple function I try just displays NOTHING. I tried dataframe.head(), dataframe['km'], dataframe[3:6], etc. No errors, just a big bowl of nothing on my terminal.

Edit to add example code:

import pandas as pd  import numpy as np  import matplotlib.pyplot as plt  pd.set_option('max_columns', 50)  #df=pd.read_csv('data.csv')  data = {'km': [240000, 139800, 150500, 185530, 176000, 114800, 166800, 89000, 144500, 84000, 82029, 63060, 74000, 97500, 67000, 76025, 48235, 93000, 60949, 65674, 54000, 68500, 22899, 61789], 'price': [3650, 3800, 4400, 4450, 5250, 5350, 5800, 5990, 5999, 6200, 6390, 6390, 6600, 6800, 6800, 6900, 6900, 6990, 7490, 7555, 7990, 7990, 7990, 8290]}  df = pd.DataFrame(data, columns=['km', 'price'])  print (df)  df.info()  df[2:5]  df["km"]  

Answer 1

You have to use:

print(dataframe.head()) print(dataframe['km']) print(dataframe[3:6]) 

Without the print statement python is just selecting the data but not doing anything with it.
