Practice - 5 Tasks

1fill in blank

easy

💡 Hint

Common Mistakes

Using float() instead of int() changes the type to float.

Using str() keeps it as a string, no conversion.

Using bool() converts to True or False, not a number.

Use int() to convert a string containing digits to an integer.

💡 Hint

Common Mistakes

Using int() keeps it as an integer.

Using str() converts to a string, not a number.

Using bool() converts to True or False.

Use float() to convert an integer to a floating-point number.

Fix the error in the code to convert the float 3.14 to a string.

Python

text = [1](3.14)
print(text)

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

💡 Hint

Common Mistakes

Using int() causes loss of decimal part.

Using float() keeps it as a float, no string conversion.

Using bool() converts to True or False.

Use str() to convert any value to a string.

4fill in blank

hard

Fill both blanks to create a dictionary with words as keys and their lengths as values, but only for words longer than 3 letters.

Python

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

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

Alen(word)

B<=

C>

Dword

Attempts:

💡 Hint

Common Mistakes

Using '<=' includes words of length 3 or less.

Using 'word' instead of 'len(word)' gives the word itself, not length.

Using 'len(word)' with '<=' filters wrong words.

Use len(word) to get the length, and > to filter words longer than 3 letters.

5fill in blank

hard

Fill all three blanks to create a dictionary with uppercase keys and values only if the value is greater than 0.

Python

result = {{ [1]: [2] for k, v in data.items() if v [3] 0 }}

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

Dk.lower()

Attempts:

💡 Hint

Common Mistakes

Using 'k.lower()' makes keys lowercase, not uppercase.

Using '<' instead of '>' filters wrong values.

Using 'k' instead of 'k.upper()' keeps original case.

Use k.upper() for uppercase keys, v for values, and > to filter values greater than zero.
