'how shall i call out this function using string format method?

i'm learning Python and have began with Google's Python Automation Beginner course. Idk if i chose it right but im already in week 4 and now have started facing confusion.

Fill in the gaps in the nametag function so that it uses the format method to return first_name and the first initial of last_name followed by a period. For example, nametag("Jane", "Smith") should return "Jane S."

  def nametag(first_name, last_name):
return("___.".format(___))

Solution 1:^[1]

def nametag(first_name, last_name):
    return '{} {}.'.format(first_name, last_name[0])

will put the arguments of format in place of the brackets.

Solution 2:^[2]

Please try this:

def nametag(first_name, last_name):

    return "{} {last_name}.".format(first_name, last_name=last_name[0])


print(nametag("Jane", "Smith"))

out put:
Jane S.

Solution 3:^[3]

def nametag(first_name, last_name):
    return("{} {}.".format(first_name, last_name[0]))

print(nametag("Jane", "Smith")) 
# Should display "Jane S." 
print(nametag("Francesco", "Rinaldi")) 
# Should display "Francesco R." 
print(nametag("Jean-Luc", "Grand-Pierre")) 
# Should display "Jean-Luc G."

Solution 4:^[4]

You should use an fstring. It's more modern (and easier to read) than format().
f'{first_name} {last_name[0]}.'

Solution 5:^[5]

def nametag(first_name, last_name):
    return("{} {[0]}.".format(first_name,last_name))

print(nametag("Jane", "Smith")) 
print(nametag("Francesco", "Rinaldi")) 

print(nametag("Jean-Luc", "Grand-Pierre"))

Solution 6:^[6]

def nametag(first_name, last_name):

return("{first_name} {last_name[0]}.".format(first_name= first_name, last_name=last_name[0]))

print(nametag("Jane", "Smith"))

Should display "Jane S."

Solution 7:^[7]

Try this out

def nametag(first_name, last_name):
    return("{}{}{}.".format(first_name," ",last_name[0]))

Solution 8:^[8]

def nametag(first_name, last_name):
    name = '{}.{}'.format(first_name, last_name)
    location = name.find('.')
    name = name[:location + 2].replace('.', ' ') + '.'
    return name

Solution 9:^[9]

Correction: Here is a very simple solution that works

def nametag(first_name, last_name):
    return("{} {:.1}.".format(first_name, last_name))
print(nametag("Jane", "Smith"))
