Step by step
Solved in 2 steps
- Assume that d refers to a dictionary. Write a statement in Python that retrieves from the dictionary the value that is associated with the key 'answer', and assigns this value to the result variable.The following statement creates an empty dictionary: mydct = {} True or FalseIn Python: The following statement creates an empty dictionary Mydectionary = { } True False
- In a dictionary, each element has two parts: a(n) _________ and a(n) _________.a. index, valueb. value, indexc. key, valued. integers, valueAssume the variable dct references a dictionary. Write an if statement that determines whetherthe key 'James' exists in the dictionary. If so, display the value that is associated with that key.If the key is not in the dictionary, display a message indicating so.Assume the following list exists: names = ['Chris', 'Katie', 'Joanne', 'Kurt'] Write a statement that uses a dictionary comprehension to create a dictionary named X in which each element contains the length of a name from the list as the key, and the corresponding name's initial character as its value.
- This is my code for a dictionary of student's test scores. def main(): #Create a dictionary with name as key #Marks as the list of values student_dictionary = \ { 'Brian': [94, 89, 92], 'Rachel': [100,90,65], 'Jon': [67.5,95,100], 'Brit': [0,78,80] , 'Gret': [65,100,78], 'Andrea': [55.5,67,79] } for key in student_dictionary.keys(): print('Name: ', key, " , Marks:", student_dictionary.get(key)) if __name__ == '__main__': main() Problem: Find and print out Rachels second score (should be a 90)Write code that iterates through a dictionary represented by the variable my_dict and prints any values (not keys!) associated with keys beginning with the letter "k" (lowercase).Which part of a dictionary element must be immutable?
- A ValueError exception is raised if you try to retrieve a value from a dictionary using a nonexistent key. True or FalseYou are given a list of courses that are currently available in BRACU that looks like the following: courses = ['CSE110','CSE111','MAT620','CS520','EEE361','CSE650','MAT5100','CSEE21','MAT3210']. All course code will have 3 digits with the department name of 3 letters. Any course code not following this rule is Invalid. Write a python program that creates a dictionary from the above list where the keys will be each department name (CSE,EEE,MAT for the above example) or Invalid. Departments will contain a list of valid courses for that department. Sample Input - No need to take input ['CSE110','CSE111','MAT620','CS520','EEE361','CSE650','MAT5100','CSEE21','MAT3210'] Sample Output : (You just need to print the resultatnt dictionary. No need to follow the format.) { 'CSE': ['CSE110','CSE111','CSE650'], 'EEE': ['EEE361'], 'MAT': ['MAT620'], 'Invalid': ['CS520','CSEE21','MAT5100','MAT3210'] }1. Course informationWrite a program that creates a dictionary containing course numbers and the room numbers ofthe rooms where the courses meet. The dictionary should have the following key-value pairs:Course Number (key) Room Number (value)CS101 3004CS102 4501CS103 6755NT110 1244CM241 1411The program should also create a dictionary containing course numbers and the names of theinstructors that teach each course. The dictionary should have the following key-value pairs:Course Number (key) Instructor (value)CS101 HaynesCS102 AlvaradoCS103 RichNT110 BurkeCM241 LeeThe program should also create a dictionary containing course numbers and the meeting timesof each course. The dictionary should have the following key-value pairs:Course Number (key) Meeting Time (value)CS101 8:00 a.m.CS102 9:00 a.m.CS103 10:00 a.m.NT110 11:00 a.m.CM241 1:00 p.m.The program should let the user enter a course number, then it should display the course’s roomnumber, instructor, and meeting time.
