Output of multi-line string with triple quotes

What is the output of this Python code?

Python

text = '''Hello
World
Python'''
print(text)

A Hello\nWorld\nPython

B Hello World Python

C

Hello
World
Python

D Hello\ World\ Python

💡 Hint

Triple quotes preserve new lines inside the string.

Triple quotes allow writing strings on multiple lines. The \n inside the string is interpreted as a new line, so print outputs three lines.

Output of multiple print statements

What will be printed by this code?

Python

print('Line 1')
print('Line 2')
print('Line 3')

A Line 1 Line 2 Line 3

B Line 1\nLine 2\nLine 3

C Line 1, Line 2, Line 3

D

Line 1
Line 2
Line 3

💡 Hint

Each print outputs a new line by default.

Each print statement outputs text followed by a new line, so the output is three lines with one line each.

Output of multi-line string with escape sequences

What is the output of this code?

Python

text = """First line
Second line	Tabbed
Third line"""
print(text)

A First line\nSecond line\tTabbed\nThird line

B

First line
Second line	Tabbed
Third line

C First line Second line Tabbed Third line

D First line\ Second line\ Tabbed\ Third line

💡 Hint

Escape sequences like \n and \t are interpreted inside triple quotes.

The \n creates new lines and \t adds a tab space in the output.

Identify the error in multi-line string usage

What error does this code raise?

Python

text = '''This is a multi-line string
without closing quotes
print(text)

A SyntaxError

B TypeError

C IndentationError

D NameError

💡 Hint

Check if all quotes are properly closed.

The triple quotes are not closed, so Python raises a SyntaxError.

🧠 Conceptual

How many lines does this multi-line string contain?

How many lines will the variable 'text' contain after this code runs?

Python

text = '''Line1
Line2

Line4'''

A 4

B 3

C 2

D 5

💡 Hint

Count all lines including empty ones created by \n.

The string has Line1, Line2, an empty line (because of \n\n), and Line4, so 4 lines total.

Practice

1. Which of the following is the correct way to write a string that spans multiple lines in Python?

easy

A. Use double quotes but write all text in one line only

B. Use single quotes and separate lines with commas

C. Use triple quotes like '''This is a\nmulti-line string'''

D. Use backslashes at the end of each line without quotes

Solution

1. Step 1: Understand multi-line string syntax

   Python allows strings to span multiple lines using triple quotes (either ''' or """).

2. Step 2: Check each option

   Use triple quotes like '''This is a\nmulti-line string''' correctly uses triple quotes to write a multi-line string. Other options misuse quotes or syntax.

3. Final Answer:

   Use triple quotes like '''This is a\nmulti-line string''' -> Option C

4. Quick Check:

   Triple quotes = multi-line string [OK]

Hint: Remember: triple quotes let strings span multiple lines easily [OK]

Common Mistakes:

• Using single or double quotes without triple quotes
• Trying to separate lines with commas inside quotes
• Forgetting to close triple quotes

2. Which of these code snippets correctly prints multiple lines using a multi-line string?

easy

A. print('''Line 1\nLine 2\nLine 3''')

B. print('Line 1\n' + 'Line 2\n' + 'Line 3')

C. print('Line 1\nLine 2\nLine 3')

D. print('''Line 1
Line 2
Line 3''')

Solution

1. Step 1: Understand how multi-line strings handle newlines

   Triple-quoted strings keep line breaks as typed, so actual newlines appear without \n escape sequences.

2. Step 2: Analyze each option

   print('''Line 1 Line 2 Line 3''') uses triple quotes with actual newlines inside, so it prints three lines. print('''Line 1\nLine 2\nLine 3''') uses \n inside triple quotes, which prints literal \n, not new lines. Options B and D use single quotes with \n, which print new lines correctly, but are not multi-line strings.

3. Final Answer:

   print('''Line 1 Line 2 Line 3''') -> Option D

4. Quick Check:

   Triple quotes with real newlines print multiple lines [OK]

Hint: Triple quotes keep line breaks as typed, no need for \n [OK]

Common Mistakes:

• Using \n inside triple quotes expecting line breaks
• Confusing escape sequences with actual newlines
• Using single quotes for multi-line strings

3. What will be the output of this code?

text = '''Hello
World
Python'''
print(text)

medium

A. Hello
World
Python

B. Hello\nWorld\nPython

C. Hello World Python

D. SyntaxError

Solution

1. Step 1: Understand triple-quoted string behavior

   The triple quotes preserve the line breaks inside the string as actual newlines.

2. Step 2: Predict print output

   Printing the string will show three lines: Hello, World, and Python each on its own line.

3. Final Answer:

   Hello World Python -> Option A

4. Quick Check:

   Triple quotes print multi-line text as typed [OK]

Hint: Triple quotes print text with real line breaks, not \n literals [OK]

Common Mistakes:

• Expecting \n to print literally
• Confusing string representation with print output
• Syntax errors from missing quotes

4. Find the error in this code that tries to print multiple lines:

text = '''Line 1
Line 2
Line 3'
print(text)

medium

A. Missing closing triple quotes causes SyntaxError

B. Using single quotes inside triple quotes is not allowed

C. print() function is missing parentheses

D. No error, code runs fine

Solution

1. Step 1: Check string delimiters

   The string starts with triple single quotes ''' but ends with a single quote ', causing a syntax error.

2. Step 2: Identify error type

   Python expects matching triple quotes to close the string. Mismatched quotes cause SyntaxError.

3. Final Answer:

   Missing closing triple quotes causes SyntaxError -> Option A

4. Quick Check:

   Triple quotes must open and close properly [OK]

Hint: Triple quotes must match exactly at start and end [OK]

Common Mistakes:

• Ending triple-quoted string with single quote
• Forgetting to close triple quotes
• Assuming print syntax error instead

5. You want to store a long message with multiple paragraphs in a variable and print it exactly as typed, including blank lines. Which is the best way to do this?

hard

A. Concatenate many single-line strings with + and \n

B. Use triple quotes to write the message with blank lines inside

C. Use single quotes and write all text in one line with \n

D. Use multiple print statements for each line

Solution

1. Step 1: Understand requirement for preserving formatting

   To keep multiple paragraphs and blank lines exactly as typed, the string must preserve line breaks and spaces.

2. Step 2: Choose best method

   Triple quotes allow writing multi-line strings naturally, including blank lines, without needing \n or concatenation.

3. Final Answer:

   Use triple quotes to write the message with blank lines inside -> Option B

4. Quick Check:

   Triple quotes preserve formatting best for long multi-line text [OK]

Hint: Triple quotes keep all line breaks and spaces as typed [OK]

Common Mistakes:

• Using concatenation makes code messy and error-prone
• Forgetting to add \n for new lines in single quotes
• Using multiple print statements loses single string storage
