Python 转换 str bool


参考链接: Python bool()

从数据库取出的 bool 数据 db = True 从前台url传来的 str 数据 url = “true” 

QA:比较这2个是参数是否相同? 

if str(db).lower() == url:

    pass

# str(db) 输出为 "True"    

# str(db).lower() 输出为 "true"               

还有这里注意下最好将bool转换为str 因为如果将str类型转bool时除了None和一些特殊符号为False,其余都为True 

>>> a = "false"

>>> bool(a)

True

>>> a = "true"

>>> bool(a)

True

#这种转换没有任何意义
