Is this a new thing in 3.7? Because here I get:
Apfelkiste:Tcl2018 chris$ python3
Python 3.6.1 |Anaconda 4.4.0 (x86_64)| (default, May 11 2017, 13:04:09)
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> __import__( 'sys' ).version
'3.6.1 |Anaconda 4.4.0 (x86_64)| (default, May 11 2017, 13:04:09) \n[GCC
4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)]'
>>> help( __import__( 'math' ).sin )
Help on built-in function sin in module math:
sin(...)
sin(x)
Return the sine of x (measured in radians).
The help is actually not written out to the terminal but, displayed in
the pager (less), and the first sin(...) is typeset in boldface.
