Python Online Quiz
Following quiz provides Multiple Choice Questions (MCQs) related to Python. You will have to read all the given answers and click over the correct answer. If you are not sure about the answer then you can check the answer using Show Answer button. You can use Next Quiz button to check new set of questions in the quiz.
Q 1 - What is the output for −
'you are doing well' [2:999]
Answer : D
Explanation
Slicing will never give us an error even if we give it too large of an index for the string. It will just return the widest matching slice it can.
Q 2 - What is output of following code −
num=3
while True:
if (num%0o12 == 0):
break
print(num)
num += 1
Answer : B
Explanation
we are getting output 3 to 9 because 0o12 is octal number.
Q 3 - Syntax error in python is detected by _________at _______
Answer : B
Explanation
Syntax error in python is detected by interpreter at run time.
Q 4 - What is output for − min(''hello world'')
Answer : B
Explanation
python considers a blank space character as minimum value in a string.
Q 5 - What is the output of the code?
def f():
global z
print('z is: ', z)
z=50
print('new value of global z is: ', z)
f()
print('Value of z is: ', z)
new value of global z is: 100
value of z is 100
new value of global z is: 100
value of z is 50
new value of global z is: 50
value of z is 100
new value of global z is: 50
value of z is 50
Answer : D
Explanation
Here in the above code global' keyword is used to state that z' is global variable. So when we assign a value to z in the function then the new assigned value is reflected whenever we use the value of z' in the main block or outside the function.
Q 6 - What is the output of the following code?
eval(''1 + 3 * 2'')
Answer : D
Explanation
Eval is a method used to evaluate the values entered in the braces.
Q 8 - Choose the correct syntax for reading from a text file stored in c:\scores.txt'' ?
A - Infile = open(''c:\scores.txt'',''r'')
B - Infile = open(file=''c:\\\scores.txt'', ''r'')
Answer : D
Explanation
You need to define the format in which you want to open the file. Proper path has to be declared by the user for the interpreter to reach the destination of the file.
Q 9 - Select the code for the following output?
A - Canvas.showinfo(''showinfo'', ''Programming'')
B - Tkinter.showinfo(''showinfo'' , ''Programming'')
C - Tkinter.messagebox.showinfo(''Programming'')
D - Tkinter.messagebox.showinfo(''showinfo'' , ''Programming'')
Answer : D
Answer : C
Explanation
Because Identifiers start from letter A to Z or a to z or an underscore (_) followed by more letters or zero or underscores and digits (0 to 9). Python does not allow @ or $ or % within the identifier.
