#Python算数运算符
a = 10
b = 15
# + 加
print('a + b =', a + b)
# - 减
print('a - b =', a - b)
# * 乘
print('a * b =', a * b)
# / 除
print('a / b =', a / b)
print('b / a =', b / a)
# % 取模，返回出除法的余数，余数为5
print('b % a =', b % a)
# ** 冥，返回x的y次方
print('a ** b =', a ** b)
# // 取整除，除法返回商的向下取整
print('b // a =', b // a)
print('16 // 7 =', 16 // 7)
