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.
