# 123

Example 2: convert float to int python

a = "This cannot be converted to an integer"
b = int(a)  # the interpreter raises ValueError

Example 4: convert string to number python

#INTEGERS
# Use the class int() to turn a string into a integer
s = "120"
s = int(s)
print(s+1)
#121
#FLOATS
# Use the class float() to turn a string into a float
s="2.5"
s = float(s)
print(s*2)
#5.0

value1 = "10"
value2 = 10.2

print(int(value1))
print(int(value2))
