def print_words_from_string(string): words = string.split() for word in words: print(word) # 测试代码 string = "Hello world, how are you?" print_words_from_string(string) 运行以上代码,输出结果为: 代码语言:txt 复制 Hello world, how are you?
"""This function is primarily used as a transition tool for programsbeing converted from Python 2 which supported the use of comparison functions.1. python2支持比较方法,现在不支持了。2. 需要将对比方法转化为关键方法。2. cmp_to_key 就是将对比方法转为关键方法。"""A comparison function is any ...
int(10) 是PyIntObject 的实例对象,比PyObject 多一个ob_ival 成员,PyVarObject 比PyObject 多一个int ob_size; 即表示元素个数,当然具体的 如 PyStringObject 还会有其他的成员,如下所示。可以认为 PyObject 是 整数类型等定长对象的头, PyVarObject 是 str 等不定长对象的头,如下所示,注意下面带EXTRA ...
Now, let’s convert the string to be all lower case: print(ss.lower()) Copy Output sammy shark Thestr.upper()andstr.lower()functions make it easier to evaluate and compare strings by making case consistent throughout. That way if a user writes their name all lower case, we can still...
The problem is that we have arrays of integers, and we would have to cast each individual element to a string when we print it. We can overcome this limitation with map, which takes every element in an array and runs a function against it: ".".join(map(str,mask)) By using map, ...
