Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.
Pandas Index.all()
function checks if all the elements in the index are true or not. It returns one single boolean value if axis is not specified. It returns true if each individual value in the index are true. It returns false if any of the values in the index is not true.
Note : It treats 0 as false value.
Syntax: Index.all(*args, **kwargs)
Parameters :
*args : These parameters will be passed to numpy.all
**kwargs : These parameters will be passed to numpy.all
Returns : all : bool or array_like (if axis is specified)
A single element array_like may be converted to bool.
Example #1: Use Index.all()

import pandas as pd
df = pd.Index([ 10 , 44 , 5 , 25 , 74 ])
df
|
Output :

Output :
