[Python] Display HTML class not showing inside an if-else block in Jupyter Notebook

I'm using this class to represent the dataframes in a .ipynb file:

# Handy class for DataFrame viz
class display(object):
'''
Display HTML representation of multiple objects
'''

template = '''<div style="float: left; padding: 10px;">
<p style='font-family:"Courier New", Courier, monospace'>{0}</p>{1}
</div>'''

def __init__(self, *args):
self.args = args

def _repr_html_(self):
return '\n'.join(self.template.format(a, eval(a)._repr_html_()) for a in self.args)

def __repr__(self):
return '\n\n'.join(a + '\n' + repr(eval(a)) for a in self.args)


This class is not working inside an if-else block and I don't understand why.

Can anyone give an explanation? Thx in advance!


Chunk to replicate the issue:

import pandas as pd

# Handy class for DataFrame viz

# Create a sample DataFrame with 3 rows and 5 columns
df = pd.DataFrame({
'A': [1, 2, 3],
'B': [4, 5, 6],
'C': [7, 8, 9],
'D': [10, 11, 12],
'E': [13, 14, 15]
})

# Display the DataFrame
display('df')

>>>

df

A B C D E
0 1 4 7 10 13
1 2 5 8 11 14
2 3 6 9 12 15


inside = True

if inside:
display('df')
