Str=input("enter a sentence :- ")
Count=input("enter letter/words to count in string :-")
Count=Str. count(Count)
print("Total words/letter :- ",Count)
Example (2):- For replace function practice. Try it yourself without looking at the solution.
Que - One day two friends Dhruv and Rahul are playing typing games together on there computers and Rahul said that I am very fast in typing so dhruv take a test of rahul speed typing. Dhruv given a sentence to Rahul and tell him to type without stopping his fingers.
