# 数字关系运算
# a = 98
# b = 93
# print(a == b)  # False
# print(a != b)  # True
# print(a > b)  # True
# print(a >= b)  # True
# print(a < b)  # False
# print(a <= b)  # False

# 特殊关系运算符比较
#公式理解:x 关系 y 关系 z——> 等价:x关系y and y关系z
print(5 > 3 > 2)  # 理解:5>3 and 3>2  #True
print(5 > 3 < 2)  # 理解:5>3 and 3<2  #False
