How to clone or copy a list? With new_list = my_list, you don't actually have two lists. The assignment just copies the reference to the list, not the actual list, so both new_list and my_list refer to the same list after the assignment. To actually copy the list, you have various possibilities:
Alex Martelli's opinion (at least back in 2007) about this is, that it is a weird syntax and it does not make sense to use it ever. ;) (In his opinion, the next one is more readable). This is a little slower than list() because it has to find out the datatype of old_list first. Obviously the slowest and most memory-needing method, but sometimes unavoidable. Example: Output: original: ['foo', Foo(5), 'baz'] list.copy(): ['foo', Foo(5)] slice: ['foo', Foo(5)] list(): ['foo', Foo(5)] copy: ['foo', Foo(5)] deepcopy: ['foo', Foo(1)]Ref: https://bit.ly/37iWI38 Write a Python program to check a triangle is equilateral, isosceles or scalene. Note :
An equilateral triangle is a triangle in which all three sides are equal.
A scalene triangle is a triangle that has three unequal sides.
An isosceles triangle is a triangle with (at least) two equal sides.

We will take the three angles of the triangle as input. We have to see whether a triangle, with these angles, is valid or not. To understand this code, you need to be familiar with the conditions of a possible triangle. First, let us proceed with this, before diving deep into the problem. Properties of Angles of a Valid TriangleA triangle, as you would all know, is a polygon with three vertices and three sides along with three external and internal angles. This polygon has a lot of properties to satisfy its validity but let us see here the ones for angles of a triangle :
All these conditions have to be true for the validity of the triangle. We will be using these properties to check if the given angles can constitute a valid triangle in the given task. Implementation of the Properties in the TaskIn this task, we will use the conditions we discussed above and if the three angles fulfill the conditions of triangle validity, we will print that the triangle is valid. If not, we will print negative,i.e, the triangle is not possible. We will take the three angles as input from the user; you may also use the angle of your choice as default. The approach is as follows :
Python program: Possibility of Triangle with Given Angles# function to check validity of triangle with the given angles def Triangle(x, y, z): # to check whether sum of angles are 180 and each angle # not equal to 0 if(x != 0 and y != 0 and z != 0 and (x + y + z)== 180): # Checking sum of 2 angles greater than the third if((x + y)>= z or (x + z)>= y or (y + z)>= x): print("Yes,triangle is valid") else: print("No,triangle not possible") else: print("No,triangle not possible") # Main Code x = int(input("Enter the first angle: ")) y = int(input("Enter the second angle: ")) z = int(input("Enter the third angle: ")) Triangle(x,y,z)ConclusionOutput : Enter the first angle: 50 Enter the second angle: 60 Enter the third angle: 70 Yes,triangle is validHere, we took the input for three angles as 50,60,70 and see that 50+60+70 gives us 180. Also, all the values are non-zero and 50+60 > 70. Hence, all conditions are true and print “Yes, triangle is valid“. Output : Enter the first angle: 45 Enter the second angle: 45 Enter the third angle: 80 No,triangle not possibleHere, we took the input of three angles as 45,45,80 and see that all the values are non-zero and 45+45>80. But, 45+45+80 is not equal to 180 degrees. Hence, one of the conditions fails, and “No, triangle not possible” is printed.
