💡 Hint

Common Mistakes

Using '-' instead of '+' causes subtraction.

Using '*' or '/' will multiply or divide instead of adding.

Adding two Series uses the + operator to sum values by index.

💡 Hint

Common Mistakes

Using '+' adds instead of subtracting.

Using '*' or '/' changes the operation to multiply or divide.

Subtracting s2 from s1 uses the '-' operator.

💡 Hint

Common Mistakes

Using '+' or '-' changes the operation to addition or subtraction.

Using '/' divides instead of multiplying.

Element-wise multiplication uses the '*' operator between Series.

4fill in blank

hard

Fill both blanks to create a new Series with squares of values from s for indices where values are greater than 3.

Data Analysis Python

result = {word: s[word][1]2 for word in s.index if s[word] [2] 3}

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

💡 Hint

Common Mistakes

Using '*' instead of '**' does multiplication, not power.

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

Use '**' to square the value and '>' to filter values greater than 3.

5fill in blank

hard

Fill all three blanks to create a dictionary of index labels in uppercase with their values, filtering values less than 5.

Data Analysis Python

result = [1]: [2] for [3], val in s.items() if val < 5}}

💡 Hint

Common Mistakes

Using item instead of idx causes undefined variable error.

Using val as key or idx.upper() as loop variable causes errors.

Use idx.upper() for keys, val for values, and idx as the loop variable for index labels.
