Binary Sequence Types — bytes, ...Strings in Python are technically a type of list — one in which each character is a separate element. This means each character in a string can be individually accessed by index, like with the elements in a list: myString = "Hello, World!" var_1 = myString[0] var_2 = myString[7:] var_3 = myString[1:4]You can extract a substring from a string by slicing with indices that get your substring as follows: string [start:stop:step] start - The starting index of the substring. stop - The final index of a substring. step - A number specifying the step of the slicing. The default value is 1. Indices can be positive or negative numbers.In Python, parsing strings is a common task when working with text data. String parsing involves splitting a string into smaller segments based on a specific delimiter or pattern. This can be easily done by using a split () method in Python.
