The len() function in Python helps in getting the length of any type of data, like a string, list, or tuple. The len() function is used to get the length (number of elements) of an object like a string, list, dictionary, or set. Example 1: Python 1 2 3 4 # Using len() ...
In this example,my_listcontains three elements, so the highest valid positive index is 2 (my_list[2]). Attempting to accessmy_list[3]results in anIndexErrorbecause there is no fourth element in the list. The Python interpreter's response to such an error is to halt the execution of the...
a nice string representation of the object. | If the argument is a string, the return value is the same object. | | Method resolution order: | str | basestring | object | | Methods defined here: | | __add__(...) | x.__add__(y) <==> x+y | | __contains__(...) | x...
In the first example, you call the built-in abs() function to get the absolute value of -7. Then, you compute 2 to the power of 8 using the built-in pow() function. These function calls occupy a single logical line and return a value. So, they’re expressions. Finally, the call...
