Escape characters in output in Python - Practice Problems & Coding Challenges

Challenge - 5 Problems

What is the output of this code with escape characters?

Consider the following Python code snippet. What will it print?

Python

print("Hello\nWorld")

A

Hello
World

B Hello\nWorld

C Hello World

D Hello\World

💡 Hint

Remember that \n is the escape sequence for a new line.

The \n escape character creates a new line in the output, so the print statement outputs Hello on one line and World on the next.

What does this print with tab escape character?

What is the output of this code snippet?

Python

print("Name:\tJohn")

A Name: John

B Name:\tJohn

C Name:John

D Name: John

💡 Hint

The \t escape character adds a horizontal tab space.

The \t adds a tab space between 'Name:' and 'John', so the output has extra space.

What is the output of this string with mixed escape characters?

What will this code print?

Python

print("Line1\nLine2\tTabbed\nLine3\\Backslash")

A

Line1
Line2	Tabbed
Line3\Backslash

B

hsalskcaB\3eniL
debbaT	2eniL
1eniL

C

Line1
Line2	Tabbed
Line3Backslash

D Line1 Line2 Tabbed Line3 Backslash

💡 Hint

Remember \n is new line, \t is tab, and \\ is a single backslash.

The output has three lines: 'Line1', then 'Line2' followed by a tab and 'Tabbed', then 'Line3\Backslash' with a single backslash.

What error or output does this code produce?

What happens when you run this code?

Python

print('It\'s a sunny day')

A SyntaxError

B It\'s a sunny day

C It's a sunny day

D It's a sunny day\n

💡 Hint

The backslash escapes the single quote inside single quotes.

The backslash before the single quote allows it to be part of the string, so it prints: It's a sunny day.

What is the output of this raw string with escape sequences?

What will this code print?

Python

print(r"C:\\Users\\Admin")

A C:\Users\Admin

B C:\\Users\\Admin

C C:\Users\Admin\

D C:UsersAdmin

💡 Hint

Raw strings treat backslashes as literal characters.

Raw strings (prefixed with 'r') treat backslashes as literal characters, not escape sequences. Thus, r"C:\\Users\\Admin" prints C:\\Users\\Admin.

Practice

1. What does the escape character \n do in a Python string?

easy

A. Ends the string

B. Inserts a tab space

C. Prints a backslash character

D. Starts a new line in the output

Solution

1. Step 1: Understand escape characters

   Escape characters are special sequences starting with a backslash that change how text is displayed.

2. Step 2: Identify the effect of \n

   The sequence \n means a new line, so it moves the cursor to the next line when printing.

3. Final Answer:

   Starts a new line in the output -> Option D

4. Quick Check:

   \n = new line [OK]

Hint: Remember \n means new line, like pressing Enter [OK]

Common Mistakes:

• Confusing \n with tab space
• Thinking \n prints literally as \n
• Mixing up \n with backslash

2. Which of the following is the correct way to print a backslash character in Python?

easy

A. print("/\")

B. print("\\")

C. print("\")

D. print("\n")

Solution

1. Step 1: Recognize backslash escape

   Backslash is an escape character, so to print it literally, you must escape it with another backslash.

2. Step 2: Check each option

   print("\\") uses \\ which prints a single backslash. print("\") is invalid syntax. print("/\") mixes slash and backslash incorrectly. print("\n") prints a new line, not a backslash.

3. Final Answer:

   print("\\") -> Option B

4. Quick Check:

   Double backslash prints one backslash [OK]

Hint: Use double backslash \\ to print one backslash [OK]

Common Mistakes:

• Using a single backslash causes syntax error
• Confusing forward slash / with backslash \
• Expecting \n to print a backslash

3. What will be the output of this code?

print("Hello\nWorld\t!")

medium

A. Hello\nWorld\t!

B. Hello
World !

C. Hello
World !

D. Hello World !

Solution

1. Step 1: Interpret escape sequences in the string

   \n creates a new line, so "Hello" and "World" appear on separate lines. \t adds a tab space before the exclamation mark.

2. Step 2: Visualize the output

   The output shows "Hello" on the first line, then "World" followed by a tab space and "!" on the second line.

3. Final Answer:

   Hello World ! -> Option C

4. Quick Check:

   \n = new line, \t = tab space [OK]

Hint: \n breaks line, \t adds spaces like tab [OK]

Common Mistakes:

• Printing escape sequences literally instead of interpreting
• Ignoring tab space effect
• Confusing \n with space

4. Find the error in this code snippet:

print("She said, "Hello!"")

medium

A. Missing escape characters for inner quotes

B. Incorrect use of single quotes

C. Extra parentheses in print

D. No error, code runs fine

Solution

1. Step 1: Analyze string quotes

   The string uses double quotes outside and inside without escaping inner quotes, causing syntax error.

2. Step 2: Fix by escaping inner quotes

   Inner quotes around "Hello!" must be escaped as \"Hello!\" or use single quotes outside.

3. Final Answer:

   Missing escape characters for inner quotes -> Option A

4. Quick Check:

   Escape inner quotes to avoid syntax error [OK]

Hint: Escape inner quotes with \" or use single quotes outside [OK]

Common Mistakes:

• Not escaping inner quotes causes syntax error
• Using mismatched quotes
• Assuming print syntax error instead of string error

5. You want to print this exact text including quotes and backslash:

He said: "Use \n for new lines."

Which print statement will produce this output?

hard

A. print("He said: \"Use \\n for new lines.\"")

B. print('He said: "Use \\n for new lines."')

C. print("He said: 'Use \n for new lines.'")

D. print('He said: "Use \n for new lines."')

Solution

1. Step 1: Identify required output characters

   The output must include double quotes around the phrase and a literal backslash followed by n (not a new line).

2. Step 2: Escape quotes and backslash correctly

   Double quotes inside string must be escaped as \". Backslash must be escaped as \\ to print literally. So \\n prints \n, not newline.

3. Step 3: Check options

   print("He said: \"Use \\n for new lines.\"") correctly escapes inner quotes and backslash. print('He said: "Use \\n for new lines."') uses single quotes outside but escapes inner quotes unnecessarily and may cause confusion. print("He said: 'Use \n for new lines.'") uses single quotes inside output, not double quotes. print('He said: "Use \n for new lines."') prints \n as newline, not literal.

4. Final Answer:

   print("He said: \"Use \\n for new lines.\"") -> Option A

5. Quick Check:

   Escape quotes and backslash to print exactly [OK]

Hint: Escape " as \" and \ as \\ to print literally [OK]

Common Mistakes:

• Not escaping backslash prints newline instead
• Confusing single and double quotes in output
• Missing escapes for inner quotes
