Enhanced input dialog

[srfpala at gmail.com]

Running Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:06:47) [MSC v.1914 32 bit (Intel)] on win32.
Under Win7 using Pyscripter 3.6.0.0 x86
Somehow  integer1 = input( "Enter first integer:\n" ) # read string  
when executed  presents a nice input dialog box  instead of a
command line prompt.   
It  provides a text box,  OK and Exit buttons, 
and I did not import wxPython.
The print command responds as expected.
How is this possible ?
What is providing this enhanced functionality ?
TIA
  Bob
