Return the lowest index in the string where substring sub is found, such that sub is contained in the slice s[start:end]. Optional arguments start and end are interpreted as in slice notation. Return -1 if sub is not found.Note: The find() method should be used only if you need to ...
Return a string which is the concatenation of the strings in the sequence seq. The separator between elements is the string providing this method. str.ljust(width[, fillchar]) Return the string left justified in a string of length width. Padding is done using the specified fillchar (default ...
we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...

Thezfill()method adds zeros (0) at the beginning of the string, until it reaches the specified length. If the value of the len parameter is less than the length of the string, no filling is done. Syntax string.zfill(len) Parameter Values ...
