Just an input in Python -

-

i've started learning python. first language, don't harsh on me if easy. can't figure out how solve this. i've programed:

a=input("enter pyramid base size ") h=input ("enter pyramid height size ") p=a*a+2*a*h print (p)

but comes out:

enter pyramid base size 2 enter pyramid height size 2 traceback (most recent call last):   file "d:\program files (x86)\python\pyramid.py", line 3, in <module>     p=a*a+2*a*h typeerror: can't multiply sequence non-int of type 'str'

the type of input received string equation, numbers needed. can convert input integer or float , math

a = int(a) h = float(h)

now might need check if input can converted number , can like:

try:   h = int(h) except valueerror:   print 'the input couldnt converted integer'

edit

so, here code should like

a = input("enter pyramid base size ") h = input ("enter pyramid height size ")  try:   = int(a)   h = int(a)   p = a*a + 2*a*h    print (p) except: valueerror:   print 'input cannot converted integer'
