Let’s check our first character string my_string1:print(any(c.isalpha() for c in my_string1)) # Check if letters are contained in string # TrueAs you can see, the logical value True has been returned, i.e. our first example string contains alphabetical letters....
Check In StringTo check if a certain phrase or character is present in a string, we can use the keywords in or not in.ExampleGet your own Python Server Check if the phrase "ain" is present in the following text: txt = "The rain in Spain stays mainly in the plain"x = "ain" in ...

In this tutorial, you'll learn the best way to check whether a Python string contains a substring. You'll also learn about idiomatic ways to inspect the substring further, match substrings with conditions using regular expressions, and search for substri
最后,我们调用函数check_chars_in_string并输出结果。 AI检测代码解析 check_chars_in_string(text,chars) 1. 测试代码 现在我们可以测试代码是否能够正确判断多个字符是否在字符串中了。 AI检测代码解析 text="Hello, World! This is a test string."chars=['a','b','c']check_chars_in_string(text,chars...

实现__getitem__足以允许按索引检索项目,并支持迭代和in运算符。__getitem__特殊方法实际上是序列协议的关键。查看Python/C API 参考手册中的这篇文章,“序列协议”部分。int PySequence_Check(PyObject *o)如果对象提供序列协议,则返回1,否则返回0。请注意,对于具有__getitem__()方法的 Python 类,除非它们是...
