Thank you so much!. I finally understood ‘functions’. I like the way you explained about the repetitive work and how functions help with that.

[rob]

Experimenting - you can combine these two lines into this and it works:
first_name_initial = get_initial(input('Enter your first name: '))
Maybe sacrificing some readability - but it seems straightforward and you don't have to use an extra variable.

You could make that code a little more efficient in the definition, by having the following :-


def get_initial(name):
return name[0:1]

Muchas gracias!
I now understand functions.

At 6:00, 'and I ask for one character' is a little confusing...Since will give nothing, rather than 1 character starting from position 3.

We aren't lazy, we are comfortably efficient.

i just wish you explained the syntax of writing functions a little more and not briefly toward the end of the video.

[VictorOlet]

With this idea of a function returning a value, aren't the earlier functions (in the video) ending with print() also returning a value? Since print() produces an output?
Trying to understand why the functions later in the video are referred to as returning values and the earlier ones are not.

[ritikadhiman]

why is there
\
this is print statement ??

Why are there hardcore coders in the comment section trying to show off to us newbies

[JKarle]

I am thinking another method could be:

initials = get_initial(first_name) + get_initial(last_name)

then you can extract the first or last initial as needed (initials[0:1])

Advantages or disadvantages?

[abdelhadiaziz]

it's possible to extract the initials using name[0].
name[x] reterns the character in position x, first character having index 0.

[adrianmuller]

Why slice the list with [0:1] instead of just using [0]?

[adriansillsii]

Anyone else getting the "name not defined" after being prompted to enter the first name?

[tursh_city]

why is datetime written like this?
datetime.datetime.now()
