如何在具有特定键的字典中添加多个值 [英] How to add multiple values in dictionary having specific key

问题描述

例如，我想为特定键添加更多值，认为我的字典是 FinalData = {} 它包含以下键值对: {'12345,70':xyz，'12345,71':pqr} 现在我想为相同的键'12345,70'添加值('abc')，以便我的最终字典成为 {'12345,70':xyz，abc，'12345,71':pqr} 我试图通过 FinalData [key] .append(value)<附加第二个值/code>却给了我

I want to add more values to specific key for example, consider my dictionary is FinalData = {} and it contains key value pair as: {'12345,70':xyz,'12345,71':pqr} and now I want to add value ('abc') for same key '12345,70'so that my final dictionary becomes {'12345,70':xyz,abc,'12345,71':pqr} I tried to append second value by FinalData[key].append(value) but it gives me

错误:AttributeError:'str'对象没有属性'append'

error: AttributeError: 'str' object has no attribute 'append'

那么他们有什么办法解决这个问题，我是python新手，请帮忙.

So is their any way to resolve this, I'm new to python please help.

推荐答案

使用列表而不是字符串:

Use a list instead of a string:

FinalData = {'12345,70': ['xyz'], '12345,71': ['pqr']}

这可行:

FinalData[key].append(value)

示例

key = '12345,70'
value = 'abc'
FinalData[key].append(value)
print(FinalData)

输出:

{'12345,70': ['xyz', 'abc'], '12345,71': ['pqr']}
