How can output to stdout be suppressed?
A semi-colon can be used to supress display of returned objects, for example
>>> 1+1
2
>>> 1+1; # No output!
However, a function that prints to stdout is not affected by the semi-colon.
>>> print('Hello!')
Hello!
>>> MyFunction()
Calculating values...
How can the output from print / MyFunction be suppressed?
Add %%capture as the first line of the cell. eg
%%capture
print('Hello')
MyFunction()
This simply discards the output, but the %%capture magic can be used to save the output to a variable - consult the docs
