Hello everyone I hope someone can explain this cod to me 
there is the variable y [ ] – list how this code works. hope I'm not too boring. Here we have an input number but since Python is the default input string then it is a string and if i type 10 for example the result is 6 which is true but do not understand how y takes this number and also what does works hier “.split” bult-in functions and in the next line we attribute the same later to the variable ‘’d’. Thanks a lot in advance

Thanks a lot in advance# calculate Q
c = 50
h = 30
# use thi formule Q = square root of [(2*c*d)/h]
import math
x = []
y = [i for i in input('give me a number: ').split(',')] # ?????
for d in y:
x.append(str(int(round(math.sqrt((2*c*float(d)/h))))))
print(','.join(x))
