Name attribute does not handle "&" within a string properly when trying to print

[turbonate]

I have a file that has customer-specified account names in it. These names will contain the "&" symbol, which creates issues when trying to use print(t). t.children will provide the name, but print(t) seems to have some parsing issues with "&" in a name.

from ete3 import Tree
t = Tree()
t.add_child(name='LIABILITIES & EQUITY')
print(t)

I get the following error:

~\AppData\Local\Programs\Python\Python39\lib\site-packages\ete3\coretype\tree.py in __str__(self)
    251     def __str__(self):

Hi, I tried the code you demonstrated and seems fine, I wonder if it could be the version issues. Mine is: ete3.1.2 python 3.6.10 & python3.7

In [1]: from ete3 import Tree ...: t = Tree() ...: t.add_child(name='LIABILITIES & EQUITY') ...: print(t)
-- /-LIABILITIES & EQUITY
