Remember to use escape characters inside quotes to avoid errors.
Raw strings (prefix with r) ignore escape characters, useful for file paths.
Summary
Escape characters let you control special text output.
Use \n for new lines, \t for tabs, and \\ for backslash.
Escape quotes inside strings to print them correctly.

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
Step 1: Understand escape characters
Escape characters are special sequences starting with a backslash that change how text is displayed.
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.
Final Answer:
Starts a new line in the output -> Option D
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
Step 1: Recognize backslash escape
Backslash is an escape character, so to print it literally, you must escape it with another backslash.
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.
Final Answer:
print("\\") -> Option B
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
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.
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.
Final Answer:
Hello
World ! -> Option C
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
Step 1: Analyze string quotes
The string uses double quotes outside and inside without escaping inner quotes, causing syntax error.
Step 2: Fix by escaping inner quotes
Inner quotes around "Hello!" must be escaped as \"Hello!\" or use single quotes outside.
Final Answer:
Missing escape characters for inner quotes -> Option A
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
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).
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.
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.
Final Answer:
print("He said: \"Use \\n for new lines.\"") -> Option A
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
