What is list [:: 1 in Python?

Whenever a programmer defines [::-1], it suggests that the program has to traverse from start to end in a given list. You can do indexing in python, which helps to slice and dice an iterable sequence such as a list or string.

What is the list in Python [:- 1?

[-1] means the last element in a sequence, which in this is case is the list of tuples like (element, count) , order by count descending so the last element is the least common element in the original collection.

Is += 1 the same as ++?

It's just two different ways of writing the same thing. i++ is just a shortcut for i += 1 , which itself is a shortcut for i = i + 1 . These all do the same thing, and it's just a question of how explicit you want to be.

How do I start index 1 in Python?

To start the for loop with index at 1 in Python use the range() with start param at 1 and for the end value use the len() which gives the length of the sequence object. With this we can start the for loop at index 1.

What is 1 vs 1.0 in Python?

Whole Numbers

{0, 1, 2, 3, 4…..} These include the natural (counting) numbers, but they also include zero. They don't include negatives or fractions, but they can describe how many cows are in a field as well as how many cows remain after they all leave.

Is 1.0 a double or float?

In c a value of 1 is an integer and 1.0 is a double, you use f after a decimal number to indicate that the compiler should treat it as a single precision floating point number.

Is 1.0 an integer in Python?

Type Conversion in Python

Here, we can see above that 1 (integer) is converted into 1.0 (float) for addition and the result is also a floating point number.
