提问by Jason
I'm trying to use pandas.DataFrame.to_csvto export a DataFrameto a .csvfile, however after running the following code there's no output:
我正在尝试pandas.DataFrame.to_csv将 a 导出DataFrame到.csv文件，但是在运行以下代码后没有输出：
collist = sve2_all.columns
path_d = 'C:\Users\Desktop\From EPD'
sve2_all.to_csv('sve2_all', path = path_d, columns = collist)

I think what you are doing won't work as the path is not being used to set the destination path and resulting csv
我认为您所做的将不起作用，因为该路径未用于设置目标路径和生成的 csv
This should work:
这应该有效：
import os
path_d = 'C:\Users\Desktop\From EPD'
sve2_all.to_csv(os.path.join(path_d, 'sve2_all.csv'))
Also, you are passing a string as the first parameter to to_csvwhich is probably confusing it also as it should be a fully qualified path or buffer for path_or_bufparameter.
此外，您将一个字符串作为第一个参数传递给to_csv它，这可能也会混淆它，因为它应该是path_or_buf参数的完全限定路径或缓冲区。
