X= {} Is it a set or a dict

It is a dictionary, if you want to declare an empty set you do it in the following way: x = set()

it's right: empty list: x = [] empty set: x = set() empty tuple: x = () empty dictionary: x = {} With data it will look like this: x = [1, 2, 3, 4] x = {1, 2, 3, 4} x = (1, 2, 3, 4) x = {'one': 1,'two':2, 'three': 3, 'four': 4}

Thanks a lot. What's the use of empty lists, sets, tuples, dicts really?

They are often used as containers to store data that will be added later during program execution. For example, you can create an empty list and then add items as the data is processed. Empty sets can be used to store unique items, empty tuples can be used as placeholders, and empty dictionaries can be used to store key-value pairs.

Thank u so much

Use float instead of int

hes askinf how to convert

base = float(input("Enter the base of the triangle: ")) height = float(input("Enter the height of the triangle: ")) area = 0.5 * base * height print("The area of the triangle is:", area)

I am still getting NoneType error

In line 1 & 2, you have been using print function which will return None. Do not user print function

U didn't give colon Print(input('enter height: '))

HELP me! The question is as follows... Find the length of the text python and convert the value to float and covert it to string?

text ="this is a text" To get the size you can use python's len function: len(text) The result can be stored in a variable: size = len(text) We convert the result to a float: print(float(size))

Thank you so much

Thanx a lot

While training the model got error of expected array 2d got 1d array instead how to resolve it

A= int(input("enter height"))

If I define a set variable with duplicate items how is it ok For eg. S= {33,44,55,33}
