来自多个列表的多个字符串

Question

我有以下内容：

import pandas as pd

Roads =['Motorways','Streets','Avenues']

Countries =  ['England','Scotland','Wales']

Visuals = ['Graph','Table']


TabNames = [pd.Series(Roads)+ pd.Series(Countries) + pd.Series(Visuals).tolist()]

print(TabNames) 

我将如何打印输出，以便像“高速公路英格兰图”，苏格兰高速公路图，“高速公路威尔士图”，“街道英格兰图”等等。

然后，如何复制输出或将其吐出到.txt文件？

Answer 1

您可以尝试此操作而无需导入任何库：

Roads = ['Motorways', 'Streets', 'Avenues']
Countries = ['England', 'Scotland', 'Wales']
Visuals = ['Graph', 'Table']

with open('result.txt', 'w') as write_file:
    for road in Roads:
        for country in Countries:
            for visual in Visuals:
                sentence = road + ' ' + country + ' ' + visual
                print(sentence)
                write_file.write(sentence)
                write_file.write('\n')
    
write_file.close()

输出：

Motorways England Graph
Motorways England Table
Motorways Scotland Graph
Motorways Scotland Table
Motorways Wales Graph
Motorways Wales Table
Streets England Graph
Streets England Table
Streets Scotland Graph
Streets Scotland Table
Streets Wales Graph
Streets Wales Table
Avenues England Graph
Avenues England Table
Avenues Scotland Graph
Avenues Scotland Table
Avenues Wales Graph
Avenues Wales Table

Answer 2

尝试以下操作：

index = pd.MultiIndex.from_product([Roads, Countries, Visuals], names = ["Roads", "Countries", "Visuals"])
pd.DataFrame(index = index).reset_index()
