In this blog post, you will find all the Solutions to the L7 questions of the Codetantra Python Programming Course. Here are the answere to these question:-
Q1:- L7/Dictionaries/Introduction to Dictionary :- Select all the correct statements from the given options.
Dictionary is a Python data type to store multiple values.
We use parenthesis 0 to define a dictionary.
In dictionary we represent an element in the (key-value) format.
Keys of the dictionary cannot be changed.
dictionary() function is used to create an empty dictionary.
Q2:- L7/Dictionaries/Accessing Elements of Dictionary :- Write the missing code in the program to retrieve the elements of the dictionary using keys.
mydict ={“name”: “Rama”, “branch”:”CSE”, “place”:”HYD”}
# Print the values of dictionary using keys
print(mydict[“name”])
print(mydict[“branch”])
print(mydict[“place”])
Q3:- L7/Dictionaries/Understanding Dictionary :- Identify the errors in given program and correct the program.
mydict={ “game”: “chess”, “dish”:”chicken”, “place”:”home”}
print (mydict[“game”])
print (mydict[‘dish’])
print(mydict[“place”])
mydict[“game”]= “cricket”
print (mydict[“game”])
Q4:- L7/Data Type Conversions/Data Type Conversion :- Write a simple program to convert given number into string char and hexadecimal and complex number.
a = int(input(“Enter a value: “))
b= int(input(“Enter b value: “))
#print a value respective string
print(a)
# print a value respective char
print(chr(a))
# print a value respective hexadecimal value
print(hex(a))
#print a and b of complex number
print(complex (a,b))
Q5:- L7/Data Type Conversions/Data Type Conversions :- Write the missing code in the given program to convert two lists into one dictionary and convert the dictionary into the set. Follow the instructions given as comment lines in the program
list1 = [“key”,”key2″,”key3″]
list2 = [“value1”, “value2”, “value3”]
print(list1)
print(list2)
mydict=zip(list1,list2)
# using zip() function we can create dictionary with two Lists (one List)
#convert dictionary into set using set() method
set1= set(mydict)
#print elements in sorted order
list3=list(set1)
print(sorted(list3))
