💡 Hint

Common Mistakes

Forgetting the quotes around the text.

Trying to print a variable that is not defined.

The print() function needs a string inside quotes to print text. So "Hello" is correct.

Common Mistakes

Putting quotes around numbers when not needed.

Using words instead of numbers.

To print a number, just write the number without quotes inside print().

💡 Hint

Common Mistakes

Leaving out quotes around text.

Using incomplete quotes like a single quote without closing.

Text must be inside matching quotes. "Python" is correct.

💡 Hint

Common Mistakes

Using minus - instead of plus +.

Putting numbers inside quotes which prints text, not sum.

To print the sum, use 2 + 3 inside print().

5fill in blank

hard

Fill all three blanks to print the message: Hello 5 times.

Python

for i in range([1]):
    print([2] * [3])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using wrong range number.

Not putting Hello inside quotes.

Using variable i instead of number for multiplication.

range(5) repeats 5 times, printing "Hello" * 5 prints Hello 5 times in one line.

Practice

1. What does the print() function do in Python?

easy

A. It displays messages or values on the screen.

B. It saves data to a file.

C. It reads input from the user.

D. It creates a new variable.

Solution

1. Step 1: Understand the purpose of print()

   The print() function is used to show messages or values on the screen, making it easy to see output from the program.

2. Step 2: Compare with other options

   Saving data, reading input, or creating variables are done by other functions, not print().

3. Final Answer:

   It displays messages or values on the screen. -> Option A

4. Quick Check:

   print() shows output [OK]

Hint: Remember: print() means show on screen [OK]

Common Mistakes:

• Confusing print() with input()
• Thinking print() saves data
• Assuming print() creates variables

2. Which of the following is the correct way to print the words Hello and World separated by a space?

easy

A. print('Hello' 'World')

B. print('Hello' + 'World')

C. print('Hello', 'World')

D. print('Hello'; 'World')

Solution

1. Step 1: Understand how print separates items

   Using commas in print() separates items with spaces by default, so print('Hello', 'World') prints "Hello World".

2. Step 2: Check other options

   print('Hello' 'World') joins strings without space; print('Hello' + 'World') concatenates without space; print('Hello'; 'World') uses invalid syntax.

3. Final Answer:

   print('Hello', 'World') -> Option C

4. Quick Check:

   Comma adds space in print() [OK]

Hint: Use commas to print multiple items with spaces [OK]

Common Mistakes:

• Forgetting commas between items
• Using semicolon inside print()
• Concatenating without spaces

3. What will be the output of this code?

print('A', 'B', 'C', sep='-')

medium

A. A B C

B. A-B-C

C. ABC

D. A-B C

Solution

1. Step 1: Understand the sep parameter in print()

   The sep parameter changes the separator between printed items. Here, it is set to '-'.

2. Step 2: Apply sep to the items

   Items 'A', 'B', 'C' will be joined with '-' between them, resulting in 'A-B-C'.

3. Final Answer:

   A-B-C -> Option B

4. Quick Check:

   sep='-' joins items with dash [OK]

Hint: sep changes space to your chosen separator [OK]

Common Mistakes:

• Ignoring sep and expecting spaces
• Confusing sep with end
• Missing quotes around separator

4. The code below gives an error. What is the problem?

print('Hello' end='!')

medium

A. Missing comma between arguments

B. end parameter cannot be used

C. Quotes are incorrect

D. print() cannot print strings

Solution

1. Step 1: Check syntax of print() arguments

   Arguments in print() must be separated by commas. Here, 'Hello' and end='!' are missing a comma.

2. Step 2: Understand correct usage

   Correct syntax is print('Hello', end='!') with a comma separating the string and the keyword argument.

3. Final Answer:

   Missing comma between arguments -> Option A

4. Quick Check:

   Separate print args with commas [OK]

Hint: Separate print arguments with commas [OK]

Common Mistakes:

• Forgetting commas between arguments
• Thinking end is not allowed
• Misplacing quotes

5. How can you print the numbers 1, 2, and 3 on the same line separated by commas, but end the line with a period instead of a newline?

hard

A. print(1, 2, 3, sep=',') print(end='.')

B. print(1, 2, 3, sep='.', end=',')

C. print(1, 2, 3, sep=', end='.')

D. print(1, 2, 3, sep=',', end='.')

Solution

1. Step 1: Use sep to set commas between numbers

   Setting sep=',' prints numbers separated by commas: '1,2,3'.

2. Step 2: Use end to replace newline with a period

   Setting end='.' prints a period instead of moving to a new line.

3. Step 3: Check argument order

   Argument order does not matter, but both sep and end must be included in the same print call.

4. Final Answer:

   print(1, 2, 3, sep=',', end='.') -> Option D

5. Quick Check:

   sep=',' and end='.' print 1,2,3. [OK]

Hint: Use sep for commas and end for period [OK]

Common Mistakes:

• Swapping sep and end values
• Using two print statements instead of one
• Forgetting to set end to '.'
