Positives, Negatives & Zeroes using lists in Python: Write a Python script which prompts the user for a sequence of integer values, and once he is finished, displays the list of positives, negatives and number of zeroes he entered. Hint: Use a while loop with a breaking condition for when the user decides to end the sequence of integers.
Positives, Negatives & Zeroes using lists in Python
print("Please enter a sequence of values. Press return/enter key after each sequence. Press q when finished.\n")
# Initialize empty lists
positives = list()
negatives = list()
zeroes = list()
# Infinite while loop with breaking condition as when-user-enters-q.
while True:
inputProvided = input("Input: ")
if inputProvided == 'q':
break
enteredNumber = int(inputProvided)
if enteredNumber > 0:
positives.append(enteredNumber)
elif enteredNumber < 0:
negatives.append(enteredNumber)
elif enteredNumber == 0:
zeroes.append(enteredNumber)
# Print the list of positives, negatives and number of zeroes he entered.
print("Positive values:", positives)
print("Negative values:", negatives)
print("Number of zeroes:", len(zeroes))
