Parameter types do not match when formatting with %. #718

name = "Alice"
age = 30
message = "My name is %s and I am %d years old." % (name, age)

I'm using the % operator for string formatting, but I keep getting a TypeError when the types of the arguments don't match the format specifiers. For example:

name = "Alice"
age = "30"  
message = "My name is %s and I am %d years old." % (name, age)
