Answer 1

Input: I have 10 dollars and 5 cents.
And you will see what is wrong.
Also numbers like 11,12...42, 100 shouldn't be changed.

Answer 2

"""here is my code. I got success after some tries, i hope it will help you"""
str = str(input())
str = str.replace(" 0 "," zero ")
str = str.replace("1 "," one ")
str = str.replace("2","two")
str = str.replace("3","three")
str = str.replace("4","four")
str = str.replace("5","five")
str = str.replace("6","six")
str = str.replace("7","seven")
str = str.replace("8","eight")
str = str.replace("9","nine")
str = str.replace("10","ten")
print(str)

Answer 3

I used string.repalce(new, old, count) function for solving this one. I guess also there are other solutions.
