Functions Vocabulary (cont) Area of a triangle (cont)

print() displays inform​ation on value the number or string can be store in height = float(​inp​ut(​'Enter the
the screen valuable height of the triangle: '))
input() receives inform​ation syntax make impossible to the phase print ('The area of the triangle
from the user error is', areaof​tri​ang​le(​base, height))
int() converts a value to an
integer Code
Python Palindrome
float() change number to be mystring = "hello"
while True:
decimal number print (mystring) ​ ​ ​ def ispali​ndr​ome​(word):
str() a list of characters firstname = input ("What is your ​ ​ ​ ​ ​ ​ ​ ​rev​erse= "​"

Area of a triangle
True , kayak is a palindrome
