split(",")}') Copy Output: List of Items in CSV =['Apple', 'Mango', 'Banana'] Python String to List of Characters Python String is a sequence of characters. We can convert it to the list of characters using list() built-in function. When converting a string to list of ...

function returns the length of the string, i.e. the number of characters. A string is like a tuple of characters. An immutable sequence of numbers-between-0-and-255 is called a bytes object. Each item in a string is a string, each item in a byte array is an integer. ...
This can be pasted into Excel, for example. Parameters --- excel : bool, default True Produce output in a csv format for easy pasting into excel. - True, use the provided separator for csv pasting. - False, write a string representation of the object to the clipboard. sep : str, defa...

bytes, or bytearray instance representing an integer literal in the given base. The literal can be preceded by '+' or '-' and be surrounded by whitespace. The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to interpret the base from the string as an integer literal....
Given a sorted array of distinct integers and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order. You must write an algorithm with O(log n) runtime complexity. ...
