程序检查数字是否为正，负，奇，偶，零？
给定数字，我们必须检查数字是偶数还是奇数，以及正数还是负数。
算法
Step 1: input number Step 2: check number is greater than equal to 0 or not. If true then positive otherwise negative and if it 0 then number is 0. Step 3: if number is divisible by 2 then it’s even otherwise its odd.
范例程式码
# Python program check if a number is Positive, Negative, Odd, Even, Zero
n=int(input("Enter Number ::>"))
if n >= 0:
if n == 0:
print("The Number Is Zero")
else:
print("This Is Positive Number")
else:
print("This Is Negative Number")
# checking for odd and even
if (n % 2) == 0:
print("{0} is Even".format(n))
else:
print("{0} is Odd".format(n))输出结果
Enter Number ::>20 This Is Positive Number 20 is Even
