Hello fellow Pythonistas, I have a question concerning import statements. My code uses matplotlib to plot the results of my calculations.
Since I want to make this plotting functionality a optional feature I would like to import matplotlib only when needed because it takes a lot of time for a TKinter-GUI to start up. And this start-up time is even longer when matplotlib is imported. I am still in doubt because PEP 008 [1] states that all imports should come right at the beginning of the code. My current code goes something like: import sys import matplotlib ## .... ## do some calcs ## ... matplotlib.plot(mydata) a optimized version would be: import sys plot_data = 'yes' # option: yes/no if plot_data == 'yes': import matplotlib else: pass ## .... ## do some calcs ## ... if plot_data == 'yes': matplotlib.plot(mydata) else: pass How would you handle such a case? What is recommended in such a case? Does anyone have experience with this? Thanks for your suggestions in advance!
