通过 Python 将不同大小列表的字典写入 CSV

Question

我想编写以下 python 词典：

dicty = {'Odd': [1,3,5,7,9], 'Even': [2,4,6], 'Operations': ['-','+','*','\']}

CSV 文件，格式如下：

当前代码：

import csv

dicty = {'Odd': [1,3,5,7,9], 'Even': [2,4,6], 'Operations': ['-','+','*','\']}

with open('data.csv', 'w') as f:
    for key in dicty.keys():
        f.write("%s, %s\n" % (key, dicty[key]))

产量：

Answer 1

您可以使用此代码：

import pandas as pd 
dictionary = {'Odd': [1,3,5,7,9], 'Even': [2,4,6], 'Operations': ['-','+','*','\']}

# These lines are because your lists are not all of the same length 
df = pd.DataFrame.from_dict(dictionary, orient='index')
df = df.transpose()

# Pandas was converting the "9" in odd to a float, this undoes that 
df["Odd"] = pd.to_numeric(df["Odd"], downcast="integer")

# index = False says don't include the index that pandas slaps onto your data  
# This writes to output.csv as you'd expect 
df.to_csv("output.csv", index = False)
