Python将txt文件保存在另一个文件夹中

Question

the following script is running well and saving the txt output in the Desktop as I am running the script from Desktop. However, I want to save the txt files to my Documents in a new folder named ASCII. How can I give the command for doing that. The 8phases.txt has the following lines-

-1  1   -1

-1  1   1

1   1   1

1   -1  1

-1  -1  -1

1   1   -1

1   -1  -1

-1  -1  1

The script-

import numpy as np
import matplotlib.pyplot as plt

D=12
n=np.arange(1,4)
x = np.linspace(-D/2,D/2, 3000)
I = np.array([125,300,75])
phase = np.genfromtxt('8phases.txt')

I_phase = I*phase

for count,i in enumerate(I_phase):
    F = sum(m*np.cos(2*np.pi*l*x/D) for m,l in zip(i,n))
    s = np.column_stack([x,F])
    np.savetxt((str(count)+'.txt'),s)

Any help please-

Answer 1

您可能应该在savetxt方法的参数中提供完整路径，例如：

np.savetxt(r"C:\ASCII\%s.txt" % count,s)

Answer 2

You can try the following

from os.path import osp
userdoc = osp.join(osp.expanduser("~"),'Documents')
np.savetxt(osp.join(userdoc, "%s.txt" % count),s)
