Write a program that asks the user for a string (only single space between words) and returns an estimate of how many words are in the string. (Hint. Count number of spaces)
Answer
str = input("Enter a string: ")
count = 0
for ch in str :
if ch.isspace() :
count += 1
print("No of words =", (count + 1))Output
Enter a string: Python was conceived in the late 1980s by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands.
No of words = 20

- From the given number, pick successive digits, using %10 and /10 to gather the digits from right to left.
- The rules for Roman Numerals involve using four pairs of symbols for ones and five, tens and fifties, hundreds and five hundreds. An additional symbol for thousands covers all the relevant bases.
- When a number is followed by the same or smaller number, it means addition. "II" is two 1's = 2. "VI" is 5 + 1 = 6.
- When one number is followed by a larger number, it means subtraction. "IX" is 1 before 10 = 9. "IIX isn't allowed, this would be "VIII". For numbers from 1 to 9, the symbols are "I" and "V", and the coding works like this. "I" , "II", "III", "IV", "V", "VI", "VII", "VIII", "IX".
- The same rules work for numbers from 10 to 90, using "X" and "L". For numbers from 100 to 900, using the symbols "C" and "D". For numbers between 1000 and 4000, using "M".
Here are some examples. 1994 = MCMXCIV, 1956 = MCMLVI, 3888= MMMDCCCLXXXVIII
