Level description Level Description Level 1 Beginner means someone who has just gone through an introductory Python course. He can solve some problems with 1 or 2 Python classes or functions. Normally, the answers could directly be found in the textbooks. Level 2 Intermediate means someone who has just learned Python, but already has a relatively strong programming background from before. He should be able to solve problems which may involve 3 or 3 Python classes or functions. The answers cannot be directly be found in the textbooks. He should use Python to solve more complex problem using more rich libraries functions and data structures and algorithms. He is supposed to solve the problem using several Python standard packages and advanced techniques. Problem template ---------------------------------------- Question Hints Solution 3. Questions ---------------------------------------- Question 1 Level 1 Question: Write a program which will find all such numbers which are divisible by 7 but are not a multiple of 5, between 2000 and 3200 both included. The numbers obtained should be printed in a comma-separated sequence on a single line. The results should be printed in a comma-separated sequence on a single line. Suppose the following input is supplied to the program: 8 Then, the output should be: 40320 Hints: In case of input data being supplied to the question, it should be assumed to be a console input.

Suppose the following input is supplied to the program: hello world and practice makes perfect and hello world again Then, the output should be: again and hello makes perfect practice world Hints: In case of input data being supplied to the question, it should be assumed to be a console input. We use set container to remove duplicated data automatically and then use sorted to sort the data. The numbers that are divisible by 5 are to be printed in a comma separated sequence. Example: 0100,0011,1010,1001 Then the output should be: 1010 Notes: Assume the data is input by console. Hints: In case of input data being supplied to the question, it should be assumed to be a console input. The numbers obtained should be printed in a comma-separated sequence on a single line. Hints: In case of input data being supplied to the question, it should be assumed python programming exercises be a console input. Suppose the following input is supplied to the program: hello world. Suppose the following input is supplied to the program: Hello world. Suppose the following input is supplied to the program: 9 Then, the output should be: 11106 Hints: In case of input data being supplied to the question, it should be assumed to be a console input. The list python programming exercises input by a sequence of python programming exercises numbers. Suppose the following input is supplied to the program: 1,2,3,4,5,6,7,8,9 Then, the output should be: 1,3,5,7,9 Hints: In case of input data python programming exercises supplied to the question, it should be assumed to be a console input. The transaction log format is shown as following: D 100 W 200 D means deposit python programming exercises W means withdrawal. Suppose the following input is supplied to the program: D 300 D 300 W 200 D 100 Then, the output should be: 500 Hints: In case of input data being supplied to the question, it should be assumed to be a console input. Write a program to check the validity of password input by python programming exercises. Following are the criteria for checking the password: 1. Minimum length of transaction password: 6 5. Maximum length of transaction password: 12 Your program should accept a sequence of comma separated passwords and will check them according to the above criteria. Passwords that match the criteria are to be printed, each separated by a comma. The tuples are input by console. The sort criteria is: 1: Sort based on name; 2: Then sort based on age; 3: Then sort by score. We use itemgetter to enable multiple sort keys. Hints: Use % operator to check if a number is even or odd. The function should just print the values only. Use keys to iterate keys in the dictionary. The function should just print the keys only. Use keys to iterate keys in the dictionary. Then the function needs to print the first 5 elements in the list. Then the function needs to print the last 5 elements python programming exercises the list. Then the function needs to print all values except the first 5 elements in the list. Use tuple to get a tuple from a list. Hints: Use if statement to judge condition. Hints: Use filter to filter some elements in a list. Use lambda to define anonymous functions. Hints: Use map to generate a list. Use lambda to define anonymous functions. Hints: Use map to generate a list. Use filter to filter elements of a list. Use lambda to define anonymous functions. Hints: Use filter to filter elements of a list. Use lambda to define anonymous functions. Hints: Use map to generate a list. Use lambda to define anonymous functions. Hints: Use staticmethod decorator to define class static method. Hints: Use class Subclass ParentClass to define a subclass. The Circle class has a method which can compute the area. Hints: Use def methodName self to define a method. The Rectangle class has a method which can compute the area. Hints: Use def methodName self to define a method. The Square class has an init function which takes a length as argument. Both classes have a area function which can print the area of the shape where Shape's area is 0 by default. Hints: To override a method in super class, we can define a method with the same name in the super class. Hints: Use raise to raise an exception. Hints: To define a custom exception, we need to define a class inherited from Exception. Both user names and company names are composed of letters only. Example: If the following email address is given as input to the program: john google. Both user names and company names are composed of letters only. Example: If the following email address is given as input to the program: john google. Example: If the following words is given as input to the program: 2 cats and 3 dogs.

Example: If the following n is given as input to the program: 5 Then, the output of the program should be: 3. Example: If the following n is given as input to the program: 5 Then, the output of the program should be: 500 In case of input data being supplied to the question, it should be assumed to be a console input. Hints: We can define recursive function in Python. Example: If the following n is given as input to the program: 7 Then, the output of the program should be: 13 In case of input data being supplied to the question, it should be assumed to be a console input. Hints: We can define recursive function in Python. Example: If the following n python programming exercises given as input to the program: 7 Then, the output of the program should be: 0,1,1,2,3,5,8,13 Hints: We can define recursive function in Python. Use list comprehension to generate a list from an existing list. In case of input data being supplied to the question, it should be assumed to be a console input. Example: If the following n is given as input to the program: 10 Then, the output of the program should be: 0,2,4,6,8,10 Hints: Use yield to produce the next value in generator. In case of input data being supplied to the question, it should be assumed to be a console input. The function should return the index of element to be searched in the list.
