In this Section we will learn how to check for only title case or proper case in a column of dataframe using istitle() function in pandas python
Let’s see with an example
Create a dataframe
## create dataframe
import pandas as pd
d = {'Quarters' : ['QUARTER1','Quarter2','quarter3','quarter4'],
'Revenue':[23400344.567,54363744.678,56789117.456,4132454.987]}
df=pd.DataFrame(d)
print df
The resultant dataframe will be
Check for title case or proper case character in column of dataframe in python
# whether only proper case or title case is present in Quarters column of dataframe in Python df['Quarters_istitle_case'] = map(lambda x: x.istitle(), df['Quarters']) print df
istitle() Function in pandas python checks whether the string consists of only title case or proper case characters.
It returns True when only title case characters are present and it returns False when it does not have only title case.
The result is stored in the Quarters_istitle_case column of the dataframe.
So the resultant dataframe will be
