This one-liner is critical! Make I look am well! Anyways here is my one-liner. https://pastebin.com/L18nXV4f

# modified: @ypeace, could you please explain how map works in your one-liner!

ypeace:


Lolz, your one liner looks better. I think it will be faster too. Map takes in a function as its first arg and an iterable (list, set) as second arg. It then passes each element in the iterable to the function.

def add_five(X):
....return x + 5

[map(add_five, [1,2,3,4,5])] //[6, 7, 8, 9, 10]

HEY GUYS,

what do you guys think about this online python course?
gurus in the house? Please advise on this.

This is the absolute beginner course https://www.edx.org/course/introduction-to-python-absolute-beginner
This are all the other python courses they have https://www.edx.org/course?search_query=python

ypeace:


Hello. I am not a guru but I think those who have taken those courses can best advice you on it. If you are a complete beginner, I will advice you to start from sololearn (a mobile app). It is good enough for basics. It is also free and easy to get started with (you don't even need to have python on your pc to get started)

Thank you so much!

I was playing around with some stuff on decision trees and came up with the following problem. I was able to work out a solution but I think my solution may be too slow and I am hoping someone might have a faster alternative. Here is the problem:

Design a function that accepts a digit; say 'n', and returns a list of lists of unary digits between 0 and 'n-1', pairs of digits between 0 and 'n-1', triples of digits between 0 and 'n-1', up until the '(n-1)-tuple' digits between 0 and 'n-1'.

for example;

if n = 2 the function return: [[0], [1], [0, 1]]
if n = 3 the function returns: [[0], [1], [2], [0, 1], [0, 2], [1, 2], [0, 1, 2]]
if n = 4 the function returns: [[0], [1], [2], [3], [0, 1], [0, 2], [0, 3], [1, 2], [1, 3], [2, 3], [0, 1, 2], [0, 1, 3], [0, 2, 3], [1, 2, 3], [0, 1, 2, 3]]

Here is my annoyingly bogus solution to the same problem: https://pastebin.com/JTrSVySJ

Please ypeace do you have access or links to ebooks that can ground me python's libraries...not those arcane books that are no different from the python documentation oh! Or alternatively do you know of good books I can buy? I need to grasp python well within a short time...your use of the itertools module there was just delicious! I salute your royal pythoness!

Thanks to your use of COMBINATIONS in ITERTOOLS, @ypeace, I was able to dig up a one-liner. https://pastebin.com/vnhbc2cJ

I guess I might just have to go the hard way of using the python documentation or the help system on my IDE before taking up serious certification courses online. Thanks for the hint!

In spirit of one-liners, create a one-liner function that accepts a dictionary with numeric values and returns a dictionary with the maximum value. For example:
i. The function accepts: {'ade': 3, 'john': 5, 'sam': 1, 'bukky': 20} and returns: {'bukky': 20}
ii. The function accepts: {'ade': 3} and returns: {'ade': 3}
iii. The function accepts: {'ade': 3, 'john': 5, 'sam': 20, 'bukky': 20} and returns: {'sam': 20, 'bukky': 20}

Have been in NYSC orientation camp in the last 23 days, my solution is attached as a pic. For those that need clarification, read the paragraph below too.

- the first part of the return statement returns the key with the highest value

- I used the sorted global function to sort the dictionary using it values in descending order. This function returns the dictionary as a list and using [0] and dic[] , I got the highest values.

- looking at the return statement, you would see that it is enclosed in a dictionary format thereby generating a dictionary of the highest key with it associated value.
