python保存文字到文件中

使用encode方法即可，举例如下：

#-*-coding:utf-8-*-

def save(re, name):
    file = open("index_cut.txt", "w")
    for k,v in re.items():
        line = "filename :" + name + "\t" + k.encode("utf-8") + "\t" + str(v) + "\n"
        file.write(line)
    file.close()

if __name__ == "__main__":
    result = {"清明": 1, "老师": 2, "天气": 3}
    save(result, "digit")

index_cut.txt:
