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,
123string = "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, whilestring.count('M')
will return 1.
