python 将列表里面的内容写入到txt文件中

方法一
将列表写入txt文件中
如下代码所示
a是一段二维列表，需要把它写入一个txt文件中，

a=[['1','9'],['2','5'],['3','3'],['2','4'],['4','3'],['1','8'],['1','9']]

t=''
with open ('N_a.txt','w') as q:
    for i in a:
        for e in range(len(a[0])):
            t=t+str(i[e])+' '
        q.write(t.strip(' '))
        q.write('\n')
        t=''

结果

数据：u = [[‘mov’, ‘push’, ‘push’, ‘call’, ‘push’, ‘push’, ‘push’, ‘call’],[‘pop’, ‘push’, ‘call’, ‘pop’, ‘retn’, ‘mov’, ‘push’, ‘call’, ‘push’],[‘push’, ‘push’, ‘call’, ‘pop’, ‘call’, ‘pop’, ‘retn’, ‘mov’, ‘push’], [‘lea’, ‘push’, ‘call’, ‘test’, ‘jnz’, ‘push’, ‘push’]]

代码：

t=''
with open ('N_a.txt','w') as q:
    for i in u:
#         print(i)           #i为['1','9']   ['2','5']
        for e in range(len(i)):
#             print(a[0])               #a[0]为['1','9']
#             print(e)                #e为0、1
            t=t+str(i[e])+' '
        q.write(t.strip(' '))
        q.write('\n')
        t=''

结果

方法二

数据：

u = [['mov', 'push', 'push', 'call', 'push', 'push', 'push', 'call'],['pop', 'push', 'call', 'pop', 'retn', 'mov', 'push', 'call', 'push'],['push', 'push', 'call', 'pop', 'call', 'pop', 'retn', 'mov', 'push'], ['lea', 'push', 'call', 'test', 'jnz', 'push', 'push']]

代码：

def text_save(filename, data):#filename为写入txt文件的路径，data为要写入数据列表.
    file = open(filename,'a')
    for i in range(len(data)):
        s = str(data[i]).replace('[','').replace(']','')#去除[],这两行按数据不同，可以选择
        s = s.replace("'",'').replace(',','') +'\n'   #去除单引号，逗号，每行末尾追加换行符
        file.write(s)
    file.close()
    print("保存文件成功") 

text_save('N_aa.txt',u)
