It is meant to be taken by beginners ### The Print Function in Python 3: ### Question (1): What will be the output of the code **Options:** 1. "Python quiz for beginners" 2. Python quiz for beginners 3. NameError**:** name "Print" is not defined 4. None of the above. **Explanation:** This will give a NameError. In Python 3 the built-in print function is defined as print () and not Print (). The letter p is not capitalised. ### Question (2): What will be the output of the code ? **Options:** 1. message 2. Python quiz for beginners 3. "Python quiz for beginners" 4. NameError: name "Print" is not defined **Explanation:** we declared a variable named message and then extracted it when printed. This is used to make the code more readable and easily reusable. ### Question (3): How do you print a string and an integer? **Options:** 1. **print("My age is " + 19)** 2. **print("My age is " + str(19))** 3. **print("My age is " + int(19))** 4. **print("My age is " + float(19))** **Explanation:** The print function can only print out data types that are the same. It will not concatenate an integer with a string. So the interger needs to be converted into a string by using str(19). ### Question (4): What will be the output of the code ? **Options:** 1. **0** 2. **10** 3. **16** 4. **1** **Explanation:** The hexadecimal numerical system is a base of 16. so 0x10 will be 16. ### Question (5): what type of iteration is the while loop used ? **Options:** 1. **definite** 2. **indefinite** 3. **indeterminate** 4. **limited** **explanation:** ### **Question (6):** what will be the output of the code? **options:** 1. ```` ``` ```` ```` ('baz', 2.0) ('bar', 2) ('foo', 1) Done. ``` ```` **2.** ('baz', 3) ('bar', 1.34) ('foo', 2.0) Done. ### Question (7): what will be the output of the function ? **options:** 1. (7,2) 2. 72 3. 9 4. NameError **Explanation:** ### **Question (8):** **which of the following assigns the value 79 to the variable prime\_number ?** **options:** 1. **prime\_number := 79** 2. **prime\_number <- 79** 3. **let prime\_number = 79** 4. **prime\_number = 79** **Explanation:** In Python a varibale does not need to be declared before it can be used. To create a variable you just assign it a value using the "=" sign. ### Question (9): What will be the result of this code ? **options:** 1. x does not equal to two. 2. **2** 3. x equals two! 4. (1+3) - 2 **Explanation:** **x = (1+3) -2 = 2. hence the first statement will be executed.** ### **Question (10):** **What will be the value of x printed ?** **Options:** 1. **3 8 2** 2. **13** 3. **3 4 5 6 7** 4. **3 5 7** **Explanation:** The range function is defined as follows: range*(start, stop, step*). So the range will start from 3 and will be incremented by 2 until it get to 8. so the sequence of numbers printed will be 3 5 7 ### Question (11): what will be the output of the code? **Options:** 1. color fruit pet 2. "color" "fruit" "pet" 3. blue apple dog 4. "blue" "apple" "dog" **Explanation:** **The for loop is the simplest way to iterate through a dictionary.** In Python 3.6 and beyond, the keys and values of a dictionary are iterated over in the same order in which they were created ### Question (12): What will be the result of the code snippet ? Options: 1. "Python for beginners" 2. srennigeb rof nohtyP 3. "srennigeb rof nohtyP" 4. None of the above Explanation: The slice statement \[: : -1] is tused to reverse the ### Question (13): What will be the result ? **Options:** 1. {1, 2, 3} 2. {1,2,3,4,5} 3. {3,4,5} 4. {1,2,3,3,4,5} **Explanation:** The python set union() returns a new set which is a combination of the distinct elements from the two sets. 3 is common from both sets and hence it will not be repeated so the result will be {1,2,3,4,5} ### Question (14): Are both conditions True ? **Options:** 1. Yes 2. No **Explanation:** The number 200 is bigger than 33 and 500 is also greater than 33. so both statements are True. ### Question (15): What will be the output of the code ? options: 1. (1880, 2560) 2. the 'break' statement is used to exit a 'for' and a 'while' loop 3. In Python, a function is defined using the block keyword "def" followed by a function's name as the block's name. a function only runs when it is called. 4. Hello From My Function 5. A list: \[1, 2, 3 6. x: 10\ y: 5 7. 938477566 : Karabo\ tebogo : 938377264\ katlego 8. the slice statement `[::-1]` means start at the end of the string and end at position 0, move with the step `-1`, *negative* one, which means one step backwards. 9. {1: 1, 2: 4, 3: 9, 5: 25}\ {1: 1, 2: 4, 4: 16, 3: 9, 5: 25}
1. {1: 1, 2: 4, 4: 16, 3: 9, 5: 25}
