How do I define a Dataframe in Python?

Question

I am doing some work in a jupyter notebook using python and pandas and am getting a weird error message and would really appreciate the help. The error I am receiving is "NameError: name 'DataFrame' is not defined"

import pandas as pd 

d = {'name': ['Braund', 'Cummings', 'Heikkinen', 'Allen'],
     'age': [22,38,26,35],
     'fare': [7.25, 71.83, 0 , 8.05], 
     'survived?': [False, True, True, False]}

df = DataFrame(d)

print(df)

Answer 1

The below code works:

import pandas as pd 

d = {'name': ['Braund', 'Cummings', 'Heikkinen', 'Allen'],
     'age': [22,38,26,35],
     'fare': [7.25, 71.83, 0 , 8.05], 
     'survived?': [False, True, True, False]}

df = pd.DataFrame(d)

print(df)

Instead of:

DataFrame(d)

You have to do:

pd.DataFrame(d)

Because you've imported pandas as 'pd'.

You can achieve the same end much better by:

df = pd.DataFrame({'name': ['Braund', 'Cummings', 'Heikkinen', 'Allen'],
                   'age': [22,38,26,35],
                   'fare': [7.25, 71.83, 0 , 8.05], 
                   'survived': [False, True, True, False]})

I removed the '?' from the 'survived' feature as it's not a good idea to have special characters in your feature names.
