Python中是有查找功能的,五种方式:in、not in、count、index,find 前两种方法是保留字,后两种方式是列表的方法。 下面以a_list = ['a','b','c','hello'],为例作介绍: string类型的话可用find方法去查找字符串位置: a_list.find('a') 1.
The True value is printed in our case since we have the search string in my_list. Example 2: Get String in List Using for LoopIn this next example, we will use a for loop to check for the search string in the list:for item in my_list: if item == search_string: print(True) ...
str_list2 = [(index,value) for index,value in enumerate(my_str)] print(str_list2) 1. 2. 3. 4. 5. 6. 7. 8. 9. 1.3字符串的拼接 我们经常要用将几个字符串连起来使用或输出,最常用的三种方式为:1.使用 + 拼接;2.使用格式化输出进行拼接;3.使用{}占位符拼接 ...
Console.WriteLine("Result: --- " + lists.Values.FindIndex(FindValue) + " ---"); Console.WriteLine("將所有資料列出"); int idx = 0; Action<ValueClass> ListAll = delegate(ValueClass obj) { Console.WriteLine(string.Format("第 {0} 個的Value值為 {1}", idx, obj.Value)); idx++;...
<1>find 检测 str 是否包含在 mystr中,如果是返回开始的索引值,否则返回-1mystr.find(str, start=0, end=len(mystr))<2>index 跟find()方法一样,只不过如果str不在 mystr中会报一个异常.mystr.index(str, start=0, end=len(mystr))<3>count 返回 str在start和end之间 在 mystr里面出现的次数my...
