Why it is not showing Error when I use dtype=str as argument in Series and passing data as a list of Strings and Floating point numbers.?

Question

when I am writing code it seems like pandas Series are supporting different data types. Which concept I am missing I this code..??

This dosent shows error

import pandas as pd
d=["javeed","meera","shareef",1.12]
pd.Series(d,range(1,5),dtype=str)

This shows Error:

i=[1,2,3,4,"Javeed"]
pd.Series(i,range(1,6),dtype=int)

I expected error for both cells but it is showing error for only one cell.

Answer 1

The first one will not give you error because 1.12 will be converted to string as you mentioned dtype = str while making series.

import pandas as pd
d=["javeed","meera","shareef",1.12]
sr = pd.Series(d,range(1,5),dtype=str)

print(sr[4])
print(type(sr[4]))

Output:

1.12   # this is string here
<class 'str'>

Reason: A float can be cast to string while a string can not be cast to float.

In second series, you have strings but you are mentioning dtype = int and since strings can't be cast into int so it is giving you error.
