I have a 15 by 15 matrix A, created using a code like the following:

for i in range(14):
    for j in range(14):
        A[i,j]=some number

By typing print(DataFrame(A)), the result doesn't show all columns. In particular, Column 5-9 are shown as "...". How could I show all columns of this matrix? Thanks!

"I have a 15 by 15 matrix A" This could mean many things. It is not useful unless you show us actual code. Please read [ask] and https://stackoverflow.com/help/minimal-reproducible-example. – Karl Knechtel Dec 25 '21 at 08:54
@KarlKnechtel Thanks! I will try to improve the question. – ExcitedSnail Dec 25 '21 at 08:55
How do you run your program? Are you using the command line? Or are you using IDLE or some other editor? It sounds like the tool you are using is eliding the output with the "...". You may need to write a for loop to manually print out the matrix in the format you want. – Code-Apprentice Dec 25 '21 at 08:56
@Code-Apprentice Thanks! I'm doing it in Pycharm. – ExcitedSnail Dec 25 '21 at 09:05
Are you using numpy? – Code-Apprentice Dec 25 '21 at 09:06
@Code-Apprentice Yes. – ExcitedSnail Dec 25 '21 at 09:07
@Code-Apprentice I tried np.set_printoptions(threshold=sys.maxsize), and it didn't work. – ExcitedSnail Dec 25 '21 at 09:10

What does "it didn't work" mean? Please refer to the links Karl gave in the first comment. – Code-Apprentice Dec 25 '21 at 09:11
@Code-Apprentice Thanks! I meant column 5-9 are still missing. But I just found the solution: print(DataFrame(A).to_string()) works. – ExcitedSnail Dec 25 '21 at 09:16
