example of a Python program on the Web that uses a dictionary in the code and share it. Post the link for the site. What is a Python dictionary? When should you use a dictionary rather than a list in Python?.What is happening in your programming example? Describe it in English as an algorithm

Research Java’s standard libraries (the APIs that are provided as part of the language,not your own custom code). Demonstrate how to add five elements of type UACar toan reference-based list implementation. Obtain the first element in the list and sendit to the println() statement. Finally, remove the first and last element in the list.

Regarding a dictionary, which of the following is not true?   This is for python.    A dictionary can contain another dictionary.   A dictionary contains key-value pairs, typically separated by a colon.   A dictionary can be modified.   The contents of a dictionary can be accessed by using either its keys or by using indexing.

Question 1: Write a python program that will take an input n from the user and then take n number of circle's radius input from the user. After that your program will calculate the area and circumference of the circle and store it in a dictionary where a key will be the circle number and value will be a list containing area first and then circumference of that circle. Finally print the dictionary. Area of circle = pi * r *r Circumference of circle = 2 * pi *r Sample input 1: 2 4 Sample Output 1: {'Circle 1': [12.566370614359172, 12.566370614359172], 'Circle 2': [28.274333882308138, 18.84955592153876], 'Circle 3': [50.26548245743669, 25.132741228718345]} Sample input 2: 4 2 3 1 Sample Output 2: {'Circle 1': [12.566370614359172, 12.566370614359172], 'Circle 2': [113.09733552923255, 37.69911184307752], 'Circle 3': [28.274333882308138, 18.84955592153876], 'Circle 4': [3.141592653589793, 6.283185307179586]}

What is the purpose of a List? Give example of a List in any language. How is it created and used?

Suppose you are given a list (1,2,3,4) and the requirement is to write a Python code segment or a function to double the numbers in that list. Comment your code to state what functional programming features you have introduced in your code.

Write a Python program that takes a dictionary as an input from the user and then prints the average of all the values in the dictionary. [You are not allowed to use len() and sum()] =================================================================== Hint (1): For taking dictionary input Approach(1): For taking dictionary as an input from the user, you may take the whole dictionary as a string using the input() function. Then you can use the split(), strip() functions and conditions to get the keys and values from the string. Finally, you can make the dictionary using the obtained data. Approach(2): If the first approach seems too difficult you can create an empty dictionary and then just run a simple loop. For each iteration ask the user for a key and a value using the input() function and keep updating the dictionary with the key and value. Hint (2): After you have a dictionary, you can use dictionary functions to get all the values from it, run loop to calculate the sum and the…
