把字典类型的数据写到文件

代码如下：
d={"姓名":"李白","年龄":"20","姓别":"女"}
d2={"姓名":"张三","年龄":"22","姓别":"男"}
s=[]
s.append(d)
s.append(d2)
with open("e:\\1.txt","w") as f:
    for i in s:
        t=""
        for k in i:
            t+=k+":"+i[k]+","
        f.write("{"+t.strip(",")+"}"+"\n")


写入文件的结果，如下：
{姓别:女,年龄:20,姓名:李白}
{姓别:男,年龄:22,姓名:张三}
