在了解了算术运算符之后编写实例进行验证，在basis目录下新建文件，命名为arithmetic.py，学习Python算术运算符的操作，在PyCharm中编写代码。
operand_a = 5
operand_b = 2
operand_c = 0

加法运算

operand_c = operand_a + operand_b
print("{} + {} = {}".format(operand_a, operand_b, operand_c))

减法运算

operand_c = operand_a - operand_b
print("{} - {} = {}".format(operand_a, operand_b, operand_c))

乘法运算

operand_c = operand_a operand_b
print("{} {} = {}".format(operand_a, operand_b, operand_c))

除法运算

operand_c = operand_a / operand_b
print("{} / {} = {}".format(operand_a, operand_b, operand_c))

取余运算

operand_c = operand_a % operand_b
print("{} % {} = {}".format(operand_a, operand_b, operand_c))

取整运算

operand_c = operand_a // operand_b
print("{} // {} = {}".format(operand_a, operand_b, operand_c))

乘幂运算

operand_c = operand_a operand_b
print("{} {} = {}".format(operand_a, operand_b, operand_c))
