接着,我们使用if…in…语句来判断substring是否存在于text字符串中。由于"world"是text字符串中的一个子字符串,所以if后面的代码将被执行。运行上述代码,输出结果为: world is in the text. 1. 总结 通过本文的介绍,我们了解了Python中用于判断元素是否存在于序列中的if…in…语句。我们可以使用这个语句来轻松地...
字符串包含操作 在Python中,可以使用in关键字来判断一个字符串是否包含另一个字符串。这种操作非常简单直观,只需要在if语句中使用即可。例如: text="Hello, world!"if"world"intext:print("Text contains 'world'") 1. 2. 3. 上面的代码会输出Text contains 'world',因为字符串"world"包含在text中。 示例代...
新建Tableau工作簿,并连接到花名册表,新建计算字段技能类型,代码如下:IF CONTAINS([技能],"剑") THEN "剑法"ELSEIF CONTAINS([技能],"刀") THEN "刀法"ELSE "其他" ENDCONTAINS函数是Tableau特有的,返回的也是一个布尔逻辑值,相当于SQL中的WHEN 技能REGEXP"[刀]" (这里是正则查找,返回的也是逻辑值),也相当...
IF CONTAINS([技能],"剑") THEN "剑法" ELSEIF CONTAINS([技能],"刀") THEN "刀法" ELSE "其他" END CONTAINS函数是Tableau特有的,返回的也是一个布尔逻辑值,相当于SQL中的WHEN技能REGEXP"[刀]"(这里是正则查找,返回的也是逻辑值),也相当于Excel中的ISNUMBER(FIND("刀","狂风刀法",1)) 6从字符串里...

Check if the Python list contains an element using in operatorTo check if the Python list contains an element using the in operator, you can quickly determine the element's presence with a concise expression. This operator scans the list and evaluates to True if the element is found, ...
Different methods to check if a string contains another string Python string supportsinoperator. So we can use it to check if a string is part of another string or not. Theinoperator syntax is: subinstr Copy It returnsTrueif “sub” string is part of “str”, otherwise it returnsFalse. ...
print(any(c.isalpha()forcinmy_string1))# Check if letters are contained in string# True As you can see, the logical value True has been returned, i.e. our first example string contains alphabetical letters. Let’s apply exactly the same Python syntax to our second string: ...
