Question

Hi everybody:

Can somebody explain to me how to remove() from a dictionary? I can delete but I can't figure out how to remove! d{'four':4,'five':5,'six':6,'seven':7}

how do i remove the second key and value 'five':5 from this dictionary?

Answer 1

There is del and pop. Delete and remove seem like the same thing to me but here is some code.

>>> d={'four':4,'five':5,'six':6,'seven':7}
>>> del d['five']
>>> d
{'four': 4, 'seven': 7, 'six': 6}
>>> item = d.pop('six')
>>> d
{'four': 4, 'seven': 7}
>>> item
6

Answer 2

Thanks, I know how to pop() it, just in the book I was reading it says you can use remove(), but it doesnt explain how? So that's what I was trying to figure... I guess no one uses remove in dictionaries then, and I shouldnt worry about it?

Answer 3

Yeah, these seem to be the standard options. I cannot find a remove function and dicts don't have a remove method. Lists on the other hand do have a remove method. May be an error in the book ... not sure.

Thanks, how long you been learning python msmithnova?

Answer 5

Only since I started doing some online courses on edX and Coursera that required it. They started toward the end of September. So about 6.5 months, but I have also done C, SML, ruby, racket, rails, html, css, php, js, cuda, ai, cryptography, algorithms, mobile robots, game theory, algebra, calculus, physics and digital audio, video and photography online courses during that time as well. I've completed 5 courses on Edx and 14 courses on Coursera during that time so only part of it was dedicated to Python. I've been busy, lol.
