x=10y=5equal=x==y # 等于 not_equal=x!=y # 不等于 greater_than=x>y # 大于 less_than=x<y # 小于 greater_than_equal=x>=y # 大于等于 less_than_equal=x<=y # 小于等于 3. 逻辑运算符 逻辑运算符用于组合多个条件,并返回布尔结果。以下是一些常见的逻辑运算符: 与:and 或:or 非:not ...
# 正确的缩进ifx>10:print("x is greater than 10")else:print("x is less than or equal to 10")# 错误的缩进ifx>10:print("x is greater than 10")else:print("x is less than or equal to 10") 解决方法:使用一个统一的缩进方式,比如四个空格或者一个制表符,并且保持代码的对齐和整洁。 2. ...
Less than:a < b Less than or equal to:a <= b Greater than:a > b Greater than or equal to:a >= b These conditions can be used in several ways, most commonly in "if statements" and loops. An "if statement" is written by using theifkeyword. ...

db.collection.find({ "field" : { $lte: value } } ); // less than or equal to : field <= value 如查询j大于3,小于4: db.things.find({j : {$lt: 3}}); db.things.find({j : {$gte: 4}}); 也可以合并在一条语句内:

1、在没有()的情况下not 优先级高于 and,and优先级高于or,即优先级关系为( )>not>and>or,同一优先级从左往右计算。 print(3>4 or 4<3 and 1==1) print(1 < 2 and 3 < 4 or 1>2 ) print(2 > 1 and 3 < 4 or 4 > 5 and 2 < 1) ...
