# Assign Multiple Values //Variable

# print(x)

# print(z)

# Output Variables
# x = "Python is "

# Create a variable inside a function, with the same name as the global variable
# x = "awesome"

# def myfunc():
#   x = "fantastic"
#   print("Python is " + x)

# myfunc()

# print("Python is " + x)

# If you use the global keyword, the variable belongs to the global scope:

# The format() method takes unlimited number of arguments, and are placed into the respective placeholders:

# print(myorder.format(quantity, itemno, price))

# You can use index numbers {0} to be sure the arguments are placed in the correct placeholders:
# quantity = 3
# itemno = 567
# price = 49.95
# myorder = "I want to pay {2} dollars for {0} pieces of item {1}."
# print(myorder.format(quantity, itemno, price))
