Python Python Basics (2015) Python Data Types String Formatting

Damn. I forget what to do.

I'm obviously missing something, but I forget what. I haven't had consistent time to work on this.

name = 'Sean'
subject = "Treehouse loves {}.format('Sean')"

Inside of .format() <โ€”- type name instead of โ€œSeanโ€

#treehouse question

#OK, now use .format() on the string "Treehouse loves {}" to put your name into the placeholder. Assign this to the #variable subject (so start with subject =).
#You do not need to print() anything.

#treehouse end of question

name = 'Sean'
subject = "Treehouse loves {}.format('Sean')" #the name should print instead of the placeholder
#if you directly place the your name, there is no value for the placeholder
#you are saving a variable at the start in the name of name with the value in it

subject = "Treehouse loves Sean"
#above is a direct print

subject = "Treehouse loves {}" #we want something to substitute {}, hence we are reserving place

#now, what do we want there is the name which is in the form of a variable, and
#when the python code runs, it will interpolate the variable with the placeholder
#and put the value at the right place
#how could be the code interpolated

subject = "Treehouse loves {}"
#have to concatenate, to join a string with the format method
#why format method - that will help interpolating the name variable with the value replacing the {}

subject = "Treehouse loves {}.format('Sean')" #replace 'Sean' with the variable name you assigned
#hint - think of where would the dot operator comes, the place you have put is wrong

absolutely, .format(name), will interpolate the name variable's value inside {} place, when the code is run.
