在Python中，正整数是大于零的整数，以下是一些关于Python正整数的基本操作和示例：

1、定义正整数

num = 5
print(num)

2、正整数的加法

num1 = 3
num2 = 4
sum = num1 + num2
print(sum)

3、正整数的减法

num1 = 7
num2 = 2
difference = num1 num2
print(difference)

4、正整数的乘法

num1 = 3
num2 = 4
product = num1 * num2
print(product)

5、正整数的除法

num1 = 8
num2 = 2
quotient = num1 / num2
print(quotient)

6、正整数的取余

num1 = 7
num2 = 3
remainder = num1 % num2
print(remainder)

7、正整数的幂运算

base = 2
exponent = 3
power = base ** exponent
print(power)

8、正整数的比较

num1 = 5
num2 = 3
print(num1 > num2)  # True
print(num1 < num2)  # False
print(num1 == num2)  # False
print(num1 != num2)  # True
print(num1 >= num2)  # True
print(num1 <= num2)  # False
