Data types are fundamental to programming languages and they define the type of values get stored in a Python variable. Here you will practice python data types which are similar to other programming languages, yet python don’t have strict type checking like C++, Java, etc. Strict type checking means the you need to declare the type of data before storing value in a variable. For example, int Num; Here ‘int’ means integer type.
It is recommended that you try these problems on your own and then compare the results. May be you may come up with a better way to solve the problem.
Program 1: Write a program that store number data types , output the type and the data.
# Filename : Number_type.py # write a program that store number types, output the values and type # number types are - integer, float , complex , and boolean integer_type = 23 float_type = 344.66 complex_type = 3 + 2j bool_type1 = True bool_type2 = False # Print values and their types print(integer_type) print(type(integer_type)) print(float_type) print(type(float_type)) print(complex_type) print(type(complex_type)) print(bool_type1) print(type(bool_type1)) print(bool_type2) print(type(bool_type2))
344.66 (3+2j) True False
Program 2: Writing a program to store ordered data types such as strings, lists, and tuples and display their value. Also, output their type information.
# Filename : ordered_data_type.py # Writing a program to display values of ordered data type with type information # python ordered types are string, list, and tuple myString = "Himalayas" myList = ["Milk","Banana", "Bread", "Chocolate", 400] myTuple = (100, "Notesformsc", "ComputerScience") # print the values and the type print(myString) print(type(myString)) print(myList) print(type(myList)) print(myTuple) print(type(myTuple))
['Milk', 'Banana', 'Bread', 'Chocolate', 400] (100, 'Notesformsc', 'ComputerScience')
Program 3: Write a program to display third letter of the string “MOUNTAIN”.
# Filename : Display_letter.py # Writing a program to display third letter of the string "MOUNTAIN" myString = "MOUNTAIN" # index start at 0; therefore, third letter is index is 2 myLetter = myString # print the output print("Third letter is",myLetter)
Third letter is U
