[英]Python 3.6. How to iterate over multiple list in a for loop and write them to a CSV File using DictWriter()
I am trying to iterate over multiple lists and save them as CSV files to open in a spreadsheet, with the first list adding it's values to columns 1, 2, and 3, and the second list adding it's values to columns 4, 5, 6. I am instead getting line 1 of list one the len(list 2) amount of times and then the second line of list 2 the same and so forth. 我正在尝试遍历多个列表并将其另存为CSV文件以在电子表格中打开,第一个列表将其值添加到第1、2和3列,第二个列表将其值添加到第4、5、6列我改为让列表1的第1行达到len(list 2)次,然后使列表2的第二行相同,依此类推。 List 2 prints out as normal and then prints again once the second line of list 1 finally prints. 列表2正常打印,然后在列表1的第二行最终打印完后再次打印。 Hopefully I explained this well enough. 希望我对此做了足够的解释。
ixl_file = open('ixalan.txt', 'r')
ixl_card = []
ixl_price = []
ixl_quantity = []
for line in ixl_file:
info = line.split("|")
ixl_card.append(info[0])
ixl_price.append(info[1])
ixl_quantity.append(info[2])
ixl_file.close()
kal_file = open('kaladesh.txt', 'r')
kal_card = []
kal_price = []
kal_quantity = []
for line in kal_file:
info = line.split("|")
kal_card.append(info[0])
kal_price.append(info[1])
kal_quantity.append(info[2])
kal_file.close()
with open('card_kingdom.csv', 'w', newline='') as ixl:
fieldnames = ['Col 1', 'Col 2', 'Col 3', 'Col 4', 'Col 5', 'Col 6']
writer = csv.DictWriter(ixl, fieldnames=fieldnames)
writer.writeheader()
"""Below is where I am having trouble add these two list in the desired format""" “”“下面是我在以所需格式添加这两个列表时遇到的问题”“”
for a,b in itertools.product(range(len(ixl_card)), range(len(kal_card))):
writer.writerow({'Col 1': ixl_card[a],
'Col 2': ixl_price[a],
'Col 3': ixl_quantity[a],
'Col 4': kal_card[b],
'Col 5': kal_price[b],
'Col 6': kal_quantity[b]
})
Your help would be much appreciated! 您的帮助将不胜感激! Let me know if you need the rest of the code. 让我知道您是否需要其余的代码。 Thanks!! 谢谢!!
This could be done using just a normal CSV writer as all of your columns appear to be in the same order: 只需使用普通的CSV编写器即可完成此操作,因为所有列的显示顺序都相同:
import csv
with open('ixalan.txt', newline='') as f_ixalan:
ixalan = list(csv.reader(f_ixalan, delimiter='|'))
with open('kaladesh.txt', newline='') as f_kaladesh:
kaladesh = list(csv.reader(f_kaladesh, delimiter='|'))
with open('card_kingdom.csv', 'w', newline='') as f_output:
csv_output = csv.writer(f_output)
csv_output.writerow(['Col 1', 'Col 2', 'Col 3', 'Col 4', 'Col 5', 'Col 6'])
for p1, p2 in zip(ixalan, kaladesh):
csv_output.writerow(p1 + p2)
Also your two .txt
files can be read using a csv.reader()
by specifying a |
您也可以使用csv.reader()
通过指定|
来读取您的两个.txt
文件|
for the delimiter. 用于分隔符。 Using zip()
takes one row from each of your two input lists, these can then be combined and written to your output CSV. 使用zip()
从两个输入列表的每一行中提取一行,然后可以将它们组合并写入输出CSV。
