Readability and efficiency

[anbarief]

there are two equal commands for each if-else block. So I just combined into one block.

I don't think this appreciably adds to the readibility. On the contrary the existing code makes it clear that there are two ways to accomplish the same thing, where one is a kwarg setting and the other is a default behavior.

Regarding efficiency, while this change may be ever so slightly more efficient, the amount is so small as to be virtually impossible to notice in any practical situation.

I am therefore going to close this without merging. @anbarief Areif, Thank you for your willingingness to contribute. It is very truly appreciated. I have merged your other PR just recently. Again, very much appreciated. Thank you!
