print('Substring count =', s.count('Th')) Output: Substring count = 3 Substring count = 3 Find all indexes of substring There is no built-in function to get the list of all the indexes for the substring. However, we can easily define one using find() function. def find_all_indexes...
To check if a Python string contains a substring, you can use theinoperator. It returnsTrueif the substring is found within the string, andFalseotherwise. For example,if "hello" in "hello world":will evaluate toTrue. Table of Contents Using the in Operator The simplest way to check if a...
How to Check if a Python String Contains a Substring In this quiz, you'll check your understanding of the best way to check whether a Python string contains a substring. You'll also revisit idiomatic ways to inspect the substring further, match substrings with conditions using regular expressio...
print(str.__contains__('ABC', 'A')) print(str.__contains__('ABC', 'D')) Output: Let’s look at another example where we will ask the user to enter both the strings and check if the first string contains the second string or substring or not. input_str1 = input('Please enter...

然而,Python 中并没有一个名为 contains 的内置函数。相反,我们使用 in 关键字来实现类似的功能。 以下是一些使用 in 关键字检查元素是否存在于不同数据结构中的示例: 检查元素是否存在于列表中: python my_list = [1, 2, 3, 4, 5] if 3 in my_list: print("3 is in the list") else: print("...
>>> list1 = str.split() #采用默认分隔符空格进行分割 >>> list1 ['python>>>', 'C++', '>', 'C', '.', '学习']list2 >>> list2 = str.split('>>>') #采用多个字符进行分割 >>> list2 ['python', ' C++ > C . 学习'] ...
字符串(String):由零个或多个字符组成的有序字符序列。 列表(List):有序的集合,可以随时添加和删除其中的元素。 元组(Tuple):与列表类似,但元组中的元素不能修改。 集合(Set):无序且不重复的元素集合。 字典(Dictionary):无序的键值对集合。 上文中 整数、浮点数、复数三种类型又称为数值型变量。
