如何在Python中使用pandas.to_csv方法指定列类型（我需要字符串）？

Question

import pandas as pd
data = {'x':['011','012','013'],'y':['022','033','041']}
Df = pd.DataFrame(data = data,type = str)
Df.to_csv("path/to/save.csv")

There result I've obtained seems as this

Answer 1

要实现这样的结果，即使不设置数据框的dtype，也可以更轻松地直接导出到xlsx文件。

import pandas as pd
writer = pd.ExcelWriter('path/to/save.xlsx')
data = {'x':['011','012','013'],'y':['022','033','041']}
Df = pd.DataFrame(data = data)
Df.to_excel(writer,"Sheet1")
writer.save()

我还尝试过其他一些方法，例如预先添加撇号或用＆＃34;引用所有字段，但它没有效果。
