ValueError: 'a' is not in list Python List Index Finding With theforLoop Method To find the index of an element in the list in Python, we can also use theforloop method. The code is: consonants=["b","f","g","h","j","k"]check="j"position=-1foriinrange(len(consonants)):i...
Find the Index of Max Value in a List Using for Loop in Python To find the index of max value in a list using for loop, we will use the following procedure. First, we will initialize a variablemax_indexto 0 assuming that the first element is the maximum element of the list. After ...
#例子:target='www.163.com'print(target.find('163'))iftarget.find('263')==-1:print('263不存在于字符串'+target+'中') 运行: C:\Users\horn1\Desktop\python\7>python find.py4263不存在于字符串www.163.com中 当然,如果仅仅是字符串里是否存在子串的话,使用 in 和 not in 操作符更好。
