例如,可以使用difflib库中的SequenceMatcher类来计算相似度: 代码语言:txt 复制 import difflib def find_similar_elements(my_list, target_element, threshold): similar_elements = [] for element in my_list: similarity = difflib.SequenceMatcher(None, element, target_element).ratio() if similarity >= ...
eval('diff_in_temp = max_temp_c - min_temp_c', inplace=True) 然后按照city_name和season这两个维度对几个指标求平均值: sample = sample.groupby(['city_name', 'season'])\ [['min_temp_c', 'max_temp_c', 'avg_temp_c', 'diff_in_temp', 'avg_wind_speed_kmh']]\ .mean().roun...
Python diff / merge basic dictionaries / lists A simple library to record changes between two simple objects and merge the changes into base object to get the changed object. Perfect if you want to store what was changed (e.g. by storing a JSON of the resulting object) and then at a ...
很容易就能想到进阶的解法:先求出两个链表的长度,计算它们的长度差 diff 。 然后让长的链表先走 diff 步,最后两个链表同时走,直到走到相同结点 node。 此时必有两种情况: node 不为空,则说明两个链表相交,且 node 就是相交结点 node 为空,则说明两个链表不相交 综上,直接返回 node 即可。 直接按照这样的...
In Python, we can easily implement something very similar using the Difflib with a single line of code. The first function I’m going to show off is context_diff().Let’s make up two lists with some string elements.s1 = ['Python', 'Java', 'C++', 'PHP'] s2 = ['Python', '...

difflib.context_diff(a, b[, fromfile][, tofile][, fromfiledate][, tofiledate][, n][, lineterm])¶ 比较a 和 b (字符串列表);返回上下文差异格式的增量信息 (一个产生增量行的 generator)。 所谓上下文差异是一种只显示有更改的行再加几个上下文行的紧凑形式。 更改被显示为之前/之后的样式。
