Anusha has written a Python program to extract and display freezing temperatures from a list of readings.
freezing_temps = []
temperatures = [3.5, -1.2, 0.0, 4.2, -3.1, 5.0]
for temp in temperatures:
if temp <= 0.0:
freezing_temps.append(temp)
print("Freezing temperatures:", freezing_temps)
Amend the code by adding a suitable comment (using the # symbol in Python) to the end of the line that corresponds to each of the following:
At the end of the line where a relational operator is evaluated.
At the end of the line where iteration begins.
At the end of the line where selection begins.
At the end of a line where a data structure is initialised.
Note: If a line meets more than one criterion, you may append multiple comments to that line.
