In this code block, we first define a listmy_listcontaining three strings: “apple”, “banana”, and “cherry”. Then, we use theinoperator to check if “banana” is present inmy_list. If it is, the code inside theifstatement is executed, printing “Found!” to the console. 2. U...

python如何将列表中的字符串变成数字 列表转集合(去重) #核心:引入库counter计数重复 from collections import Counter #查重 def find_dups(listnumber): number = Counter(listnumber) print({key for key, value in number.items() if value > 1}) # 只展示重复元素 ...
# print(222 in list1) #5、追加 # list1 = [111,222,333,444,555] # list1.append(666) # x = list1.append(777) # print(list1) # print(x) # list1.insert(2,666) # print(list1)append会加在列表最后,insert会根据索引插入
mysql中find_in_set()函数的使用 - (一)的改进版 总结: 所以如果list是常量,则可以直接用IN, 否则要用find_in_set()函数。...下面利用mysql 函数find_in_set()来解决。...注意:mysql字符串函数 find_in_set(str1,str2)函数是返回str2中str1所在的位置索引,str2必须以","分割开。...下面利用mysql ...
