# Comments use the hash symbol

# some data types are similar to VB but names are either short or different
int # Plain numbers
float # Fractional numbers with floating point (similar to Double in VB)
str # String of text
bool # Boolean value (True or False)

# Creating a variable
x = 1
y = 3.14
z = "Hello world"
a = True # Note here that true is capitalised, the same counts for False

# Instead of arrays, python has lists which can hold any type (including other lists)
x = [1, 2, 3.14, "blah", False]

# Ask user for value
name = raw_input("What is your name?")

# If, else if (elif) and else
if ...:
    ...
elif ...:
    ...
else:
    ...
    
# While loop
while ...:

# For loop
for value in my_list:

# Exception handling
try:
