问使用for循环将字典转换为csv文件

EN

import pandas as pd

# dictionaries o f data
d1 = {'item11':1, 'item12': 2}
d2 = {'item21':3, 'item22': 4}

# dictionary of the data dictionaries with names
dicts = {'d1' : d1, 'd2' : d2}

# use pandas to make a dataframe and the write data frame to csv
for a_dict in dicts:
    pd.DataFrame.from_dict(dicts[a_dict], orient="index", columns=['value']).to_csv("~/Downloads/"+a_dict+".csv", index_label="key")

# Reading into new names
new_d1 = pd.read_csv("~/Downloads/" + "d1" + ".csv", index_col=0).to_dict(orient='dict')['value']
new_d2 = pd.read_csv("~/Downloads/" + "d2" + ".csv", index_col=0).to_dict(orient='dict')['value']

assert d1 == new_d1
assert d2 == new_d2
