重复功能以提取相似信息

问题描述 投票:0回答:1

[这是我使用熊猫打开和读取json文件的方式。我真的很感谢熊猫的力量:)

import pandas as pd

df = pd.read_json("https://datameetgeobk.s3.amazonaws.com/cftemplates/EyeOfCustomer.json")

def mytype(mydict):
    try:
        if mydict["Type"]:
            return mydict["Type"]
    except:
        pass


df["myParametersType"] = df.Parameters.apply(lambda x: mytype(x))

问题是,我还需要“描述”和“默认”值以及“类型”字符串。我已经写了一个提取上述类型的函数。我真的需要再编写两个如下所示的函数吗?

def mydescription(mydict):
    try:
        if mydict["Description"]:
            return mydict["Description"]
    except:
        pass


def mydefault(mydict):
    try:
        if mydict["Default"]:
            return mydict["Default"]
    except:
        pass

df["myParametersDescription"] = df.Parameters.apply(lambda x: mydescription(x))
df["myParametersDefault"] = df.Parameters.apply(lambda x: mydefault(x))

如果字典包含三个以上的键,我将如何处理?

决赛桌应该看起来像这样...

df.iloc [:, -3:]。dropna(how =“ all”)

myParametersType    myParametersDescription myParametersDefault
pInstanceKeyName    AWS::EC2::KeyPair::KeyName  The name of the private key to use for SSH acc...   None
