Could someone help me understand the input() function? (lemmy.blahaj.zone)

I'm currently learning Python and am learning about very basic functions such as int(), float(), and input().

I have the first two down pat, but I'm struggling to understand the last. The example I'm looking at is found at 12:26 of this video:

nam = input('Who are you? ')
print('Welcome', nam)

Who are you? Chuck
Welcome Chuck

In this case, wouldn't nam be a variable equal to the text on the right side of the = sign?

In which case, if nam is equal to input('Who are you? '), then wouldn't print('Welcome', nam) just result in

Welcome input(Who are you? )?

Obviously not (nor does it work in a compiler), which leads me to believe I'm clearly misunderstanding something. But I've rewatched that section of the video several times, and looked it up elsewhere on the web, and I just can't wrap my head around it.

Could someone help me with this?

Thanks.

@EveryMuffinIsNowEncrypted i maybe wrong

input() is a python function that accepts arguments and returns value of type string.

int() and float() are special type of functions called constructor, magical.

int, or integer, on itself is a datatype like str, or string, is a datatype, to create an int you'd use its costructor int('23') something like that

int is a builtin datatype, so by typing 23, you already have an instance of int

input prints the text based as an argument to the command line, waits for the user to type text followed by a new line to the command line, and returns the text as a string as its return value.

TLDR input asks the user for text via the command line.
