print(str.__contains__('ABC', 'D')) Output: True False 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 first input string\n') input_...
A substring is the part of a string. Python string provides various methods to create a substring, check if it contains a substring, index of substring etc. In this tutorial, we will look into various operations related to substrings. Let’s first look at two different ways to create a s...

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。
In this article, we will discuss different ways to check whether the given substring exists in the string or not. 1. Quick Examples of string contains
Checking whether a string contains a substring aids to generalize conditionals and create more flexible code. Additionally, depending on your domain model - checking if a string contains a substring may also allow you to infer fields of an object, if a string encodes a field in itself. In ...
