Answer In python Only The question is inspire form the movie name frozen in which there is a land of fire and ice known as frozen land. The land is ruled by mad fire queen. Eurther more frozen land is divided into two territories. first territory is known as ice because it is always snowing and other Fire because of volcano near by area.

About beginner python programming: - Imagine that you want to send a congratulations message and would like to repeat those congratulations many timestimes in the message. Something like “Happy Birthday!! Happy Birthday!! Happy Birthday!! ..." until fullyour friend's screen. You can write once and copy and paste. Then you notice, there in the middleof the way, that you typed wrong...Ouch! Now that you know how to use Python to make it work for you,do a function that receives as input a text and the desired number of repetitions and returns astring composed of n repetitions of this text. - so I know how to input a specific word in python and multiply it by a number but not how to input a string as a variable (which can be any word, text, expression) and multiply it.
