💡 Hint

Common Mistakes

Forgetting quotes around the text

Trying to print without quotes

In Python, text must be inside quotes to be printed as a message.

Python

fruits = [[1]]

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

Aapple, banana, cherry

B"apple", "banana", "cherry"

C'apple', 'banana', 'cherry'

D"apple" "banana" "cherry"

💡 Hint

Common Mistakes

Missing commas between items

Not using quotes around strings

Lists need items separated by commas and each item as a string inside quotes.

3fill in blank

Fix the error in the code to check if a number is even.

Python

if number [1] 2 == 0:
    print("Even number")

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

A+

B//

C*

D%

Attempts:

💡 Hint

Common Mistakes

Using // which does floor division

Using * or + which are arithmetic but not remainder

The modulus operator % gives the remainder. If remainder is 0, number is even.

4fill in blank

hard

Fill both blanks to create a dictionary of squares for numbers 1 to 5.

Python

squares = {x: x[1]2 for x in range(1, 6) if x [2] 2 != 0}

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

A**

B%

C!=

D==

Attempts:

💡 Hint

Common Mistakes

Using * instead of ** for power

Using == instead of != for odd check

Use ** for power and % to check if number is odd (remainder not zero).

5fill in blank

hard

Fill all three blanks to filter and transform a dictionary of words and their lengths.

Python

result = [1]: [2] for word in words if len(word) [3] 3}

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

Aword.upper()

Blen(word)

C>

Dword

💡 Hint

Common Mistakes

Using word.upper() changes keys unnecessarily

Using < instead of > in condition

Use the word as key, its length as value, and filter words longer than 3 letters.

Practice

1. Why is Python considered easy to learn for beginners?

easy

A. Because it uses simple and clear words similar to English

B. Because it requires complex symbols and punctuation

C. Because it only works on Windows computers

D. Because it needs special hardware to run

Solution

1. Step 1: Understand Python's language style

   Python uses simple words and clear rules that look like English sentences.

2. Step 2: Compare with other languages

   Unlike some languages with many symbols, Python is easy to read and write.

3. Final Answer:

   Because it uses simple and clear words similar to English -> Option A

4. Quick Check:

   Simple English-like syntax = Easy to learn [OK]

Hint: Think: Python code reads like English sentences [OK]

Common Mistakes:

• Thinking Python needs special hardware
• Believing Python uses many complex symbols
• Assuming Python only runs on Windows

2. Which of the following is the correct way to write a simple Python print statement?

easy

A. printf('Hello World')

B. echo 'Hello World'

C. console.log('Hello World')

D. print('Hello World')

Solution

1. Step 1: Identify Python's print syntax

   Python uses the function print() with parentheses and quotes for text.

2. Step 2: Check other options

   Other options are commands from different languages (echo for shell, console.log for JavaScript, printf for C).

3. Final Answer:

   print('Hello World') -> Option D

4. Quick Check:

   Python print uses print() function [OK]

Hint: Remember: Python print always uses parentheses [OK]

Common Mistakes:

• Using echo or console.log instead of print
• Omitting parentheses in print
• Using printf which is not Python syntax

3. What will be the output of this Python code?

if 5 > 2:
    print('Yes')
else:
    print('No')

medium

A. No

B. Yes

C. 5 > 2

D. SyntaxError

Solution

1. Step 1: Evaluate the condition 5 > 2

   Since 5 is greater than 2, the condition is True.

2. Step 2: Follow the if-else logic

   Because the condition is True, the code inside the if block runs, printing 'Yes'.

3. Final Answer:

   Yes -> Option B

4. Quick Check:

   5 > 2 is True, so output = Yes [OK]

Hint: Check if condition is true or false to pick output [OK]

Common Mistakes:

• Confusing indentation causing SyntaxError
• Choosing 'No' instead of 'Yes'
• Thinking code prints the condition itself

4. Find the error in this Python code:

if 10 > 5
print('Greater')

medium

A. print should be uppercase

B. Wrong comparison operator

C. Missing colon ':' after if condition

D. Indentation is incorrect

Solution

1. Step 1: Check syntax of if statement

   Python requires a colon ':' at the end of the if condition line.

2. Step 2: Identify missing colon

   The code misses ':' after 'if 10 > 5', causing a syntax error.

3. Final Answer:

   Missing colon ':' after if condition -> Option C

4. Quick Check:

   if statements need ':' at end [OK]

Hint: Look for missing ':' after if condition [OK]

Common Mistakes:

• Thinking print must be uppercase
• Believing comparison operator is wrong
• Ignoring indentation errors here

5. How does Python's indentation style help beginners write code?

hard

A. It removes the need for extra symbols like braces, making code cleaner

B. It forces beginners to write code in one long line

C. It hides errors by ignoring spaces

D. It requires special software to manage indentation

Solution

1. Step 1: Understand Python's indentation rules

   Python uses indentation (spaces) to group code blocks instead of braces or symbols.

2. Step 2: Benefits for beginners

   This makes code easier to read and write because it looks clean and organized.

3. Final Answer:

   It removes the need for extra symbols like braces, making code cleaner -> Option A

4. Quick Check:

   Indentation replaces braces = cleaner code [OK]

Hint: Indentation groups code without extra symbols [OK]

Common Mistakes:

• Thinking indentation hides errors
• Believing code must be one line
• Assuming special software is needed
