Python中將變量按行寫入txt文本中

案例一:python

講數組a 循環寫入名稱爲2.txt的文檔中數組

# -*-coding:utf8-*-

import requests
from lxml import etree

a=[1,2,3,4,5,6]

print(a)

for i in a:
    f = open('C:/Users/Beckham/Desktop/python/2.txt','a')
    f.write('\n'+str(i))
    f.close()

腳本執行結果編碼

腳本spa

f = open('C:/Users/Beckham/Desktop/python/2.txt','a')

一行'a',表明追加模式'a',能夠實現屢次寫入。即每次執行都會在上一行的基礎上,換行寫入。還有一個模式,在'w'寫入模式下,當咱們下次寫入變量時,會覆蓋本來txt文件的內容.net

 

若是要按行寫入,咱們只須要再字符串開頭或結尾添加換行符'\n'便可,參見code

f.write('\n'+str(i))

 

案例二:xml

當須要寫入的數據須要編碼的時候,不然會提示「'gbk' codec can't encode character '\xa0' in position 51: illegal multibyte sequence」blog

# -*-coding:utf8-*-
# encoding:utf-8utf-8

 

.....................#省略中間部分文檔

test3=test2+test#把連接和提取碼拼接成一條數據
        print(test3)
        with open('C:/Users/Beckham/Desktop/python/1.txt', 'a',encoding='utf-8') as w:
            w.write('\n'+test3)
            w.close()

咱們就須要對打開的txt文本進行編碼處理
