You can alternately use the following syntax for slicing: obj[start:stop:step] For example, py_string ='Python'# contains indices 0, 1 and 2 print(py_string[0:3])# Pyt # contains indices 1 and 3 print(py_string[1:5:2])# yh ...
SyntaxError: invalid syntax Sometimes strings go over several lines. Python provides us with various ways of entering them. In the next example, a sequence of two strings is joined into a single string. We need to use backslash①or parentheses②so that the interpreter knows that the statement ...

my_string = "Python" reversed_string = my_string[::-1] print(reversed_string) # nohtyP Slicing syntax is [start:stop:step]. In this case, both start and stop are omitted, i.e., we go from start all the way to the end, with a step size of -1. As a result, the new string...
