Counting

Let's consider some other methods that can be applied to strings. One of them can help us count the number of appearances of some symbol/substring within a string.

To count the number of symbol/substring in string use .count(symbol/substring) method. For example,


              123
            
string = "String Manipulation in Python"
print("letter i appeared", string.count('i'), "times in the string.")
print("letter t appeared", string.count('t'), "times in the string.")

Note
This method is case-sensitive to symbols. For the example above, string.count('m') will return 0, while string.count('M') will return 1.

Task

You are given string "Introduction to Python". You need to calculate the number of symbols 'o' and 't' in this string.
