【问题描述】：

我想将信息写入文本文件，字典键，我在字典中（一个字符串）并根据值移动它，字典值。字典值是位置（索引为 1 抱歉）。


with open("testing.txt", "w", encoding="utf-8") as file:
    for k,v in dico_order.items():
        if v == str(1):
            file.write(k+",,,,,"+"\n")
        if v == str(2):
            file.write(","+k+",,,,"+"\n")
        if v == str(3):
            file.write(",,"+k+",,,"+"\n")
        if v == str(4):
            file.write(",,,"+k+",,"+"\n")
        if v == str(5):
            file.write(",,,,"+k+","+"\n")
        if v == str(6):
            file.write(",,,,,"+k+"\n")

【解决方案1】：

with open("testing.txt", "w", encoding="utf-8") as file:
    for k,v in dico_order.items():
        column_count = counter*","
        file.write(column_count[:v] + k + column_count[v:] + "\n")

这似乎有效
