category1 = ''
category1_tmp = ['a','b',c','d']
for n in category1_tmp:
category1 &= n + '|'
django error : unsupported operand type(s) for &=: 'str' and 'str'
what i want : a|b|c|d
how can I solve?
You can join the elements together with:
category1 = '|'.join(category1_tmp)
For a list ['a', 'b', 'c', 'd'] this will result in category1 = 'a|b|c|d'.
