python - 从字典的键和值形成 Pandas 数据框

Question

我有一个 python dict:

{'key1':'val1', 'key2':'val2', 'key3':'val3', 'key4':'val4'}

我想将其转换为这样的数据框:

col1   col2
key1    val1
key2    val2
key3    val3
key4    val4

我该怎么做？

Answer 1

import pandas as pd
data={'key1':'val1', 'key2':'val2', 'key3':'val3', 'key4':'val4'}
df=pd.DataFrame(list(zip(data,data.values())), columns =['col1', 'col2'])
print(df)
