使用writelines在Ipython的文本文件中写入数值参数行？

Question

I am trying to write lines in software (spaceclaim) that has IPython embedded, perhaps with not with all libraries available.

I am trying to write two parameters in two rows under each other, but since they are numbers, I should use str(a) for them, but I can not use \n between the two parameters to change the line. What happens is that I can write only one parameter to a text file but if I want more than one, then Python concatenates all in one line and ignores the comma.

import os
loc=os.getcwd()
filename = loc1+ '\\params.txt'

tw= [str(A), str(B)]
outfile = open(filename, "w")
outfile.writelines(tw)
outfile.close()

Answer 1

Why do you make a list? Just use a string.

tw = str(A) + '\n' + str(B)
with open(filename, 'w')as outfile:
    outfile.writelines(tw)
    outfile.close()

And I just want to say: Open a file in w mode means that when you write something it overwrites everything. Maybe your looking for a which means append.

Second you have loc =os.getcwd() and then you use filename = loc**1** + '\\params.txt'

And more little thing. You can use / instead of \\ in a path.
