How many hashes (#) will the following snippet send to the console? var = 1 while var < 10: print("#") var = var << 1

var = 1
while var < 10:
    print("#")
    var = var << 1

• one
• four
• eight
• two

Explanation: Let’s analyze this example:

• the var variable is assigned the integer value of 1,
• the while loop begins comparing 1 < 10, and since it is True, the loop is entered,
• a first # is printed on the console,
• the var variable is binary shifted 1 position to the left, and it is now 2,
• the while loop compares 2 < 10, and since it is True, the loop is entered,
• a second # is printed on the console,
• the var variable is binary shifted 1 position to the left, and it is now 4,
• the while loop compares 4 < 10, and since it is True, the loop is entered,
• a third # is printed on the console,
• the var variable is binary shifted 1 position to the left, and it is now 8,
• the while loop compares 8 < 10, and since it is True, the loop is terminated,
• a fourth # is printed on the console,
• the var variable is binary shifted 1 position to the left, and it is now 16,
• the while loop compares 16 < 10, and since it is False, the loop is terminated.
