Apparently this code is not good enough can someone help me?

The second loop basically just creates the same content that’s already in line so it wants you to print that again instead.

I wonder what it would say to

name = "World"
print(f"+{'':-^{len(name)}}+\n|{name}|\n+{'':-^{len(name)}}+")

Drop the second loop entirely and just do print(line + '+') again at the end - line and lin2 contain the exact same string so it's unnecessary to construct it twice.

consider

line += "-" * len(name)

Finish putting the + in the line and print it out again:

name = 'World'
line = '+'
for _ in name:
    line += '-'
line += '+'
print(line)
print('|' + name + '|')
print(line)

Strings also can be repeated with a * operator:

name = 'World'
line = '+' + '-'*len(name) + '+'
print(line)
print('|' + name + '|')
print(line)
