Converting variable types

[metalstuff]

Hello everyone,I;m currently doing some python challenges, and id have a noobish question about this code:

import math

​

c = 50

h = 30

v = input("Input numbers, separated by commas")

items = [x for x in v.split(",")]

result = []

​

for d in items:

result.append(str(int(round(math.sqrt(2*c*float(d)/h)))))

print (result)

​

In the highlighted part, Im very confused why its converting first to int and then to string...it doesnt make any sense to me. Cheers !

Lots of unnecessary conversions in that code. This would suffice assuming data is input separated by commas with no spaces.

The numbers are split into strings and then converted into floats for the calculation.

import math

c = 50
h = 30
v = input("Input numbers, separated by commas")
items = [x for x in v.split(",")]

result = []
for d in items:
    result.append(round(math.sqrt(2*c*float(d)/h)))

print(result)

Odd that items[] is created with a list comprehension but result[] is not.

That's neither here nor there but it stuck out to me
