Count all characters in string python

Finally, python offers a variety of so-called predicate methods, which take no arguments, and return 1 if all the characters in a string are of a particular type, and 0 otherwise. These functions, whose use should be obvious from their names, include isalnum, isalpha, isdigit, islower, isspace, istitle, and isupper. Similar to a string that can contain many characters, a list is a container that can store many values. Unlike NumPy arrays, lists are built into the language (so we don't have to load a library to use them). We create a list by putting values inside square brackets and separating the values with commasGet count array from the second string which stores the count of chars from the second string. b. Check in the input string if it contains characters from count array with frequency > 0 if yes skip it and copy remaining char into input string. c. After getting this add \0 to remove any extra characters after output string (Null termination).

In Python, strings are ordered sequences of character data, and thus can be indexed in this way. Individual characters in a string can be accessed by specifying the string name followed by a number in square brackets ([]). String indexing in Python is zero-based: the first character in the string has index 0, the next has index 1, and so on ...
