Why the result is not the same in Python and Sublime Text 3?

[0xdolan]

When testing your module, the result in Sublime Text 3 and Python IDLE is the same and none of them show the Day name (for instance: Jomeh), but when using the Python or CMD directly to work with the same code, it works fine!
Test:

from persiantools.jdatetime import JalaliDate
from datetime import datetime
print(datetime.today()) # Output: 2018-08-24 12:33:20.700418
print(JalaliDate.today()) # Output: 1397-06-02
print(JalaliDate(1369, 7, 1)) # Output: 1369-07-01

when using cmd => __repr__
when using print => __str__
