Python3 prints two backslash

Question

My goal is to print a backslash in Python3. My input is

links22 = ['1',"n","nkf"]
treee = ['<img src={} \\>'.format(i) for i in links22]
print(treee)

The output that I get is:

['<img src=1 \\>', '<img src=n \\>', '<img src=nkf \\>']

The output that I want is:

['<img src=1 \>', '<img src=n \>', '<img src=nkf \>']

And when I try:

print("\\")

The output is:

I want to figure out why the first output is \ and in the second is .

Actually this is correct, if you print the results, there should only be one backslash. — mkrieger1, Oct 31 '19 at 11:25
Does this answer your question? [Python prints two backslash instead of one](https://stackoverflow.com/questions/58639925/python-prints-two-backslash-instead-of-one) — Riccardo Bucco, Oct 31 '19 at 11:27
Actually if you print your strings from the list - they will be printed with one slash only. e.g. `for item in treee: print(item)` will give you results that you expect — ymochurad, Oct 31 '19 at 11:27
html tags end with `/` forward slash. If that's what your building. — Rithin Chalumuri, Oct 31 '19 at 11:31

That is because you are printing an array, not a string. If you print a string then this apply the escape character.

but a example of how do it would be:

...
print(*treee)
# print(*treee, sep=",") # if you want custom separator

When you perform print(treee), what you are seeing is an escaped representation of the backslash in each of the elements in the list.

If you do this instead:

for a_tree in treee:
    print(a_tree)

you will see the single backslash as expected.
