I'm trying to check is any item of a list starts with a certain string. How could I do this with a for loop? IE:
我试图检查列表中的任何项目是否以某个字符串开头。我怎么能用 for 循环做到这一点?IE:
anyStartsWith = False
for item in myList:
if item.startsWith('qwerty'):
anyStartsWith = True
回答by SeanJohn
If you want to do it with a for loop
如果你想用 for 循环来做
anyStartsWith = False
for item in myList:
if item[0:5]=='qwerty':
anyStartsWith = True
the 0:5 takes the first 6 characters in the string you can adjust it as needed
0:5 取字符串中的前 6 个字符,您可以根据需要对其进行调整
