具有嵌套列表值的字典到单个值列表

Question

I am trying to make single list of values in dictionary for each key. Bellow is problem. I am trying to parse list in Jinja and looks better to convert them into one before taking to template.

Problem:

{'EFTPOS': [[10.0, 5.0], 15.0], 'StoreDeposit': [[5.0, 6.0], 11.0]}

Result:

{'EFTPOS': [10.0, 5.0, 15.0], 'StoreDeposit': [5.0, 6.0, 11.0]}

Answer 1

Please try this code snippet.I have defined a method to remove the nested list and convert it into a flat list.

output = []
def rmNest(ls): 
    for i in ls: 
        if type(i) == list: 
            rmNest(i) 
        else: 
            output.append(i)
    return output


a_dict = {'EFTPOS': [[10.0, 5.0], 15.0], 'StoreDeposit': [[5.0, 6.0], 11.0]}

new_dict = {}

for i in a_dict:
    new_dict[i] = rmNest(a_dict[i])
    output = []
