python字符串如何判断相等

1.is来判断groupName = params['groupName'] ##groupName的值是'url'

reqBody['dim'] = groupName

print("reqBody_dim-SummaryListHandler", reqBody['dim'])

## ('reqBody_dim-SummaryListHandler', u'url')

print("reqBody_dim_url-SummaryListHandler", ('url' is reqBody['dim']))

## ('reqBody_dim_url-SummaryListHandler', False)

if groupName is 'url':

打印如下，看到通过is判断是false

('reqBody_dim-SummaryListHandler', u'url')

('reqBody_dim_url-SummaryListHandler', False)

2.id 和 in

看到用in可以判断两个字符串相等print("groupName:",groupName)

reqBody['dim'] = groupName

print("reqBody_dim-SummaryListHandler", reqBody['dim'])

print("reqBody_dim_url_is-SummaryListHandler", ('url' is groupName))

print("reqBody_dim_url_id-SummaryListHandler", (id('url')==id(groupName)))

print("reqBody_dim_url_in-SummaryListHandler", ('url' in groupName))

('groupName:', u'url')

('reqBody_dim-SummaryListHandler', u'url')

('reqBody_dim_url_is-SummaryListHandler', False)

('reqBody_dim_url_id-SummaryListHandler', False)

('reqBody_dim_url_in-SummaryListHandler', True)
