This set of Python Multiple Choice Questions & Answers (MCQs) focuses on “Formatting – 1”.
1. What is the output of the code snippet shown below?
X=”hi” print(“05d”%X)
a) 00000hi
b) 000hi
c) hi000
d) error
View Answer
Explanation: The code snippet shown above results in an error because the above formatting option works only if ‘X’ is a number. Since in the above case ‘X’ is a string, an error is thrown.
2. Consider the snippet of code shown below and predict the output.
X=”san-foundry” print(“%56s”,X)
a) 56 blank spaces before san-foundry
b) 56 blank spaces before san and foundry
c) 56 blank spaces after san-foundry
d) no change
View Answer
Explanation: The formatting option print(“%Ns”,X) helps us add ‘N’ number of spaces before a given string ‘X’. Hence the output for the code snippet shown above will be 56 blank spaces before the string “san-foundry”.
3. What is the output of the following expression if x=456?
print("%-06d"%x)
a) 000456
b) 456000
c) 456
d) error
View Answer
Explanation: The expression shown above results in the output 456.
4. What is the output of the following expression if X=345?
print(“%06d”%X)
a) 345000
b) 000345
c) 000000345
d) 345000000
View Answer
Explanation: The above expression returns the output 000345. It adds the required number of zeroes before the given number in order to make the number of digits 6 (as specified in this case).
5. Which of the following formatting options can be used in order to add ‘n’ blank spaces after a given string ‘S’?
a) print(“-ns”%S)
b) print(“-ns”%S)
c) print(“%ns”%S)
d) print(“%-ns”%S)
View Answer
Explanation: In order to add ‘n’ blank spaces after a given string ‘S’, we use the formatting option:(“%-ns”%S).
6. What is the output of this expression if X= -122?
print("-%06d"%x)
a) -000122
b) 000122
c) –00122
d) -00122
View Answer
Explanation: The given number is -122. Here the total number of digits (including the negative sign) should be 6 according to the expression. In addition to this, there is a negative sign in the given expression. Hence the output will be – -00122.
7. What is the output of the following expression if the value of x is 34?
print(“%f”%x)
a) 34.00
b) 34.0000
c) 34.000000
d) 34.00000000
View Answer
Explanation: The expression shown above normally returns the value with 6 decimal points if it is not specified with any number. Hence the output of this expression will be: 34.000000 (6 decimal points).
8. What is the result of the expression shown below if x=56.236?
print("%.2f"%x)
a) 56.00
b) 56.24
c) 56.23
d) 0056.236
View Answer
Explanation: The expression shown above rounds off the given number to the number of decimal places specified. Since the expression given specifies rounding off to two decimal places, the output of this expression will be 56.24. Had the value been x=56.234 (last digit being any number less than 5), the output would have been 56.23.
9. What is the output of this expression if x=22.19?
print("%5.2f"%x)
a) 22.1900
b) 22.00000
c) 22.19
d) 22.20
View Answer
Explanation: The output of the expression above will be 22.19. This expression specifies that the total number of digits (including the decimal point) should be 5, rounded off to two decimal places.
10. The expression shown below results in an error. State whether this statement is true or false.
print("-%5d0",989)
a) True
b) False
View Answer
Explanation: The expression shown above does not result in an error. The output of this expression is -%5d0 989. Hence this statement is incorrect.
