问题
I want to prevent a function to print in iPython notebook.
In standard python one can prevent printing some lines of code as answered in the question: To prevent a function from printing in the batch console in Python However this method do not work in iPython notebook, losing the output until a restart of the Kernel.
The most similar feature I found is to avoid a full cell to display using the magic function:
%%capture capt
However this magic function blocks the whole cell, is there any way in iPython notebook to avoid printing just some of the lines within the code?
回答1:
You could use io.capture_output:
from IPython.utils import io
with io.capture_output() as captured:
foo()
to capture stdout and stderr for only those lines within the with-statement.
