windows - python3 合并好的列表，放入到一个列表问题????

Question

遍历好的3个列表：

keys = ['a','b','c','d','e']
values = [1,2,3,4,5]
values_1 = [11,22,33,44,55]

但是我想把遍历好的列表放在一个列表试了几种都不知道怎么弄代码如下:

keys = ['a','b','c','d','e']
values = [1,2,3,4,5]
values_1 = [11,22,33,44,55]



add_text = []

for keys,value,value1 in zip(keys,values,values_1):
    print('{}--{}--{}'.format(keys,value,value1))

    # add_text.append(keys+value+value1)
    # add_text.append(keys,value,value1)

但是都报错，劳驾您的指导。

然后怎么写入text文件呢

Answer 1

s=''
for a,b,c in zip(keys,values,values_1):
    print('{}--{}--{}'.format(a,b,c))
    s+='{}--{}--{}'.format(a,b,c)+'\n'

a--1--11
b--2--22
c--3--33
d--4--44
e--5--55

open('test.txt','w').write(s)

Answer 2

python3

>>> keys = ['a','b','c','d','e']
>>> values = [1,2,3,4,5]
>>> values_1 = [11,22,33,44,55]
>>> txt='\n'.join(('--'.join(map(str,x))for x in zip(keys,values,values_1)))
>>> print(txt)
a--1--11
b--2--22
c--3--33
d--4--44
e--5--55
>>> open('test.txt','w').write(txt)
44
>>>

csv

>>> import csv
>>> with open('test.txt','w') as w:
    cw=csv.writer(w, delimiter='-')
    cw.writerows(zip(keys,values,values_1))

    
>>> print(open('test.txt','r').read())
a-1-11

b-2-22

c-3-33

d-4-44

e-5-55


>>> 

一句搞定

csv.writer(open('test.txt','w'), delimiter='-').writerows(zip(keys,values,values_1))

Answer 3

add_text.append((keys,value,value1))

Answer 4

add_text.append(keys+value+value1) 这句报错是因为三种数据类型不一致，不可以直接相加。add_text.append(keys,value,value1) 这句报错是因为list.append只接受一个参数而代码中给出了三个。如果希望生成一个包含元组的列表，每个元组包含这三个变量的话，可以直接用zip

>>> a = ['a','b','c','d','e']
>>> b = [1,2,3,4,5]
>>> c = [11,22,33,44,55]
>>> zip(a, b, c)
[('a', 1, 11), ('b', 2, 22), ('c', 3, 33), ('d', 4, 44), ('e', 5, 55)]
