# Python - Format - Strings

# String Format
'''
    In python we cannot combine strings and numbers with '+'
    Also as we learned in the Python Variables chapter, we cannot combine strings and numbers with +.
    But we can combine strings and numbers by using the format() method!
    The format() method takes the passed arguments, formats them, and places them in the string where the placeholders {} are.
''' 
age = 36
txt = "My name is John, and I am {}"
print(txt.format(age))

print('----------------------------------------------------------------')
    # The format() method takes unlimited number of arguments, and are placed into the respective placeholders.
quantity = 3
itemno = 567
price = 49.95
myorder = "I want {} pieces of item {} for {} dollars."
print(myorder.format(quantity, itemno, price))

print('----------------------------------------------------------------')
    # 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))
