What I need is to iterate on my list in order to create list of tuples like this: new_list=[('hello','001', 3), ('word','003',1), ('boy','002', 2) ('dad','007',3), ('mom','005', 3), ('honey','002',2)] You can use list comprehension for that: new_list =...
Here we iterate over all dictonaries in list. For every dictionary we iterate over its .items() and extract the key and value and then we construct a tuple for that with (key,)+val. Whether the values are strings or not is irrelevant: the list comprehension simply copies the reference ...
您可以使用itertools模块中的itertools.groupby函数将元组列表转换为字典,其中键是列表中唯一的值,值是具有相同值的元组列表。 fromitertoolsimportgroupbydefconvert_to_dict(tuple_list):# Group the tuples by their first element (the key)groups=groupby(tuple_list,key=lambdax:x[0])# Create an empty dictio...
