我们将算数运算符和赋值符号放在一起介绍。Q.27. 解释 Python 中的逻辑运算符Python 中有三个逻辑运算符：and、or、notQ.28. 解释 Python 中的成员运算符使用 in 和 not in 运算符我们可以判断某个值是否在成员中。Q.29. 解释 Python 中的身份运算符这是非常常见的 Python 面试题，用下面的示例来回答.is ...
questions = ['name', 'quest', 'favorite color']answers = ['lancelot', 'the holy grail', 'blue']for q, a in zip(questions, answers):print('What is your {0}? It is {1}.'.format(q, a))要反向遍历一个序列，首先指定这个序列，然后调用 reversed()函数：for i in reversed(range(1...

(是的,这是正确的代码,仔细一看:该else条款属于for循环,不是的if。陈述) 当循环使用,该else条款有更多的共同点与 else一个条款try声明比它认为的 if语句:一个try语句的else时候也不例外条款发生运行和循环的else条款时没有运行break 发生。有关try语句和异常的更多信息,请参阅 处理异常。 该continue声明也是从C...

if (res == NULL) { ... an exception occurred ... } else { Py_DECREF(res); } Note that since PyObject_CallObject() always wants a tuple for the argument list, to call a function without arguments, pass "()" for the format, and to call a function with one argument, surround the...
2.1. if / elif / else x=int(raw_input("Please enter an integer:"))#获取行输入 if x>0: print '正数' elif x==0: print '零' else: print '负数' 此外C语言中类似"xxx?xxx:xxx"在Python中可以这样写 >>>number=8 >>>print "good" if 8==number else "bad" #当满足if条件时返回"good...
It’s worth noting that literals in Python are immutable, meaning that their values cannot be changed once they are created. For example, if you writex = 5and then try to change the value ofxto something else, you will get an error. However, you can still create new variables with new...
for q, a in zip(questions, answers): print('What is your ? It is .'.format(q, a)) 要反向遍历一个序列,首先指定这个序列,然后调用 reversed() 函数: for i in reversed(range(1, 10, 2)): print(i) 要按顺序遍历一个序列,使用 sorted() 函数返回一个已排序的序列,并不修改原值: ...
