利用Python将list列表写入文件并读取的方法汇总_python

l=["A","B","C","D"]
 
f=open("k.txt","w")
 
f.writelines(l)
f.close()

l=["A","B","C","D",1,2,3]
 
f=open("k.txt","w")
 
f.write(str(l))
f.close()

l=["A","B","C","D"]
 
f=open("k.txt","w")
 
for line in l:
    f.write(line+'\n')
f.close()

l=["A","B","C","D"]
str = '\n'
f=open("k.txt","w")
f.write(str.join(l))
f.close()

for line in l:
    if "0" in next or "1" in next：

import csv
import codecs
def data_write_csv(file_name, datas):#file_name为写入CSV文件的路径，datas为要写入数据列表
    file_csv = codecs.open(file_name,'w+','utf-8')#追加
    writer = csv.writer(file_csv, delimiter=' ', quotechar=' ', quoting=csv.QUOTE_MINIMAL)
    for data in datas:
        writer.writerow(data)
    print("保存文件成功，处理结束")

#  将数据写入新文件
def data_write(file_path, datas):
    f = xlwt.Workbook()
    sheet1 = f.add_sheet(u'sheet1',cell_overwrite_ok=True) #创建sheet
    
    #将数据写入第 i 行，第 j 列
    i = 0
    for data in datas:
        for j in range(len(data)):
            sheet1.write(i,j,data[j])
        i = i + 1
        
    f.save(file_path) #保存文件
