Answer 2

Not sure if this is what you need, but it will read multipline lines of input from the console and only stop if an empty line is entered (probably doesn't work in SoloLearn, but it works in a console). Everything will be stored in the variable c.

c = ''

while True:
ui = input('>>> ').strip()
if ui != '':
c += ui + '\n'
else:
# remove last exit character
c = c[:-1]
break

print(c)
