\t produce eight gap but tab only produce four gap

[liuzhiheng]

The code is:

print("Hello world\n\tHello world")

The result is:

Output:
Hello world
        Hello world

but I want this \t result

Output:
Hello world
    Hello world

I found the answer in another forum, use

print("Hello world\n\tHello world".expandtabs(4))

I think this is Python default.So,How to change this defualt setting.

I don't think it is a python setting. The call to print sends tab characters to the output stream. If the console prints 8 spaces when it receives a tab character, it doesn't have anything to do with python, unless you are running the code in a python IDE such as Idle. In my bash terminal, if I write a C program that prints the same output, it also inserts 8 spaces.

Same problem with bash's echo command

Output:
λ echo -e 'foo\n\tbar'
foo
        bar

Edit: Actually, I've found a solution for the linux terminal here. It suffices to type tabs -4 to change the terminal's setting. For example

Output:
λ tabs -4
λ echo -e 'foo\n\tbar'                                                                      
foo
    bar
λ python3 -c "print('foo\n\tbar')"
foo
    bar

It Worked!
