You can go with formatted string literals ("f-strings") since Python 3.6

f"Hi {name}, you are {age}"

Or string formatting

"Hi {}, you are {}".format(name, age)
"Hi {name}, you are {age}".format(name=name, age=age)

Or format specifiers

"Hi %s, you are %d" % (name, age)

not sure why no one is just posting it f'name is {name} and age is {age}' Single or double quotes

Hey @amandae (https://teamtreehouse.com/amandae), There are many ways to format a string (https://docs.python.org/3/tutorial/inputoutput.html#input-and-output) in Python. The f-strings (https://docs.python.org/3/tutorial/inputoutput.html#formatted-string-literals), formatted string literals, is the latest addition, first appearing in Python 3.6 (https://docs.python.org/3/whatsnew/3.6.html#pep-498-formatted-string-literals). The more complex (and flexible) previous method is using the str.format() (https://docs.python.org/3/tutorial/inputoutput.html#the-string-format-method) method. This is is still widely used, and has additional features (like repeatable, reorderable fields) so expect it to stick around for a long time. With the format method, the {} placeholders can taking on many forms: * as order-dependent placeholders when empty: "{} before {}".format(first, last) * as indexed-dependent placeholders when numbered: "{1} before {0}".format(goes2zero, goes2one) * as named placeholders: "{first} before {last}".format(first=goes2first, last=goes2last) So, about remembering the difference. The "f" in front of f-strings can be thought of as fancy, where it is a shortcut to the named placeholder version of format without having to add the .format(first=first, last=last) method. The "f" can also be thought of as fast, since f-stings have been optimized to be the fasted string handling in python!! Post back if you need more help. Good luck!!
