Python更改文件路径名

Question

I want to replace my folder path by a string,I am getting an error.
I tried this :

a="ram"
my_list.to_csv(r'E:\'+str(a)+'\4\mani.csv' )

Answer 1

You made string concatenation mistake. try str.format to avoid such mistakes.

import os

a = "ram"
file_path = r'E:\{a}\4\mani.csv'.format(a=a)
directory = os.path.dirname(file_path)
os.makedirs(path, exist_ok=True)
my_list.to_csv(file_path)

Answer 2

>>> a = "ram"
>>> filename = 'mani.csv'
>>> absolute_path = os.path.join('E:', '4', a, filename)
>>> my_list.to_csv(absolute_path)
