In the Python Syntax lesson where we learn about Variable and Types of Data, all the values for the variable do not contain quotation marks. However, when learning about String Formatting with %, the variables contain quotation marks.
In Python Syntax, an example of a variable containing no quotation mark is:
a = True
In Strings & Console Output, this is an example of a variable that contains a value with a quotation mark.
name = "Mike"
print “Hello %s” % (name)
