You have a list of lists:You want to compute the sum of all even numbers greater than 3. Consider the two code snippets below (with the condition left blank):Snippet-1s = 0 for row in data: for val in row: __________: s += val print(s) Snippet-2s = 0 i = 0 while i < len(data): j = 0 while _________: if data[i][j] % 2 == 0 and data[i][j] > 3: s += data[i][j] j += 1 i += 1 print(s) Which of the following conditions, when filled in the blanks in both snippets, will give the correct result?

Assume s
is a str
variable. What is the type of the expression "".join(sorted(set(s.lower()))) ?

Consider the following Python code:t = (5, [10, 20], (30, [40, 50],(30,))) Which of the following statements are valid? (Select all that apply)

Consider the below code.if x: print('x') else: if y: if z: print('z') print('y') else: print('none') Select the possible output(s) of the given code, assuming any possible values for x , y , and z .

Consider the following Python code:for i in range(1, 6): for j in range(1, 6): for k in range(1, 2): if i == j: print("-") else: print("*", end=" ") print("+") How many lines will be printed when this code is executed?

Consider the following Python code:for i in range(1, 5): for j in range(1, 5): if j == 3: break if i == 2: continue print(i, j) How many lines will be printed when this code is executed?

Consider the following Python code:P = {1, 2, 3, 4} Q = {3, 4, 5, 6} R = {4, 5, 6, 7} S = {2, 4, 6, 8}
result = ((P | Q) - R) & S print(result) How many elements will be present in result?

Consider the following snippet of code and answer the given sub-questions:def analyze(data): result = [] for item in data: if isinstance(item, tuple): total = 0 for x in item: if x % 2 == 0: total += x result.append(total) elif isinstance(item, int) and item % 2 == 1: result.append(item * 3) else: continue return result
sample = [(2, 5, 6), 7, (1, 3), 4, (8, 2, 1)] output = analyze(sample)

What is the value of output
after executing the given code?

Consider the following snippet of code and answer the given sub-questions:def analyze(data): result = [] for item in data: if isinstance(item, tuple): total = 0 for x in item: if x % 2 == 0: total += x result.append(total) elif isinstance(item, int) and item % 2 == 1: result.append(item * 3) else: continue return result
sample = [(2, 5, 6), 7, (1, 3), 4, (8, 2, 1)] output = analyze(sample)

How many times is the inner for x in item:
loop executed in total when running analyze(sample) ?

Consider the following code:def flipper(matrix): transformed = [] for row in matrix: new_row = [] for element in row: if element < 0: new_row.append(0) elif element % 2 == 0: new_row.append(element * 2) else: new_row.append(element * 3) transformed.append(new_row) result = [ val
for sub in transformed
for val in sub
if val > 5 ] return transformed, result
matrix = [[1, -2, 3], [4, 5, -6], [7, 8]] out1, out2 = flipper(matrix) print(out1) print(out2) Answer the subquestions based on the given data.

What is the value of out1
after executing the code?

Consider the following code:def flipper(matrix): transformed = [] for row in matrix: new_row = [] for element in row: if element < 0: new_row.append(0) elif element % 2 == 0: new_row.append(element * 2) else: new_row.append(element * 3) transformed.append(new_row) result = [ val
for sub in transformed
for val in sub
if val > 5 ] return transformed, result
matrix = [[1, -2, 3], [4, 5, -6], [7, 8]] out1, out2 = flipper(matrix) print(out1) print(out2) Answer the subquestions based on the given data.
