Python String handling tip, remove specific character forward and backward in string

So, this is example code for this processing

'_' character is removed in forward and backward.

Refer to code. 🤘
Thank you.

testStr = ['  Abc  ', ' ', '  ', 'A bc', 'A bc ', '    ', ' a 12 43', ' da     ', '    ', 'a2 34', ' 1 2 ']
testStr2 = ['___Abc__', '_', '__', 'A_bc', 'A_bc_', '_____', '_a_12_43', '_da____', '__', 'a2_34', '_1_2_']

def removeTFoward(str, T):
    if len(str) == 0:
        return str
    if str[0] == T:
        return removeTFoward(str[1:],T)
    else:
        return str

def removeTBackword(str, T):
    if len(str) == 0:
        return str
    if str[-1] == T:
        return removeTBackword(str[:-1],T)
    else:
        return str

for n, v in enumerate(testStr2):
    str = removeTFoward(v, '_')
    str = removeTBackword(str, '_')
    if len(str) == 0:
        print('nothing')
    else:
        print(str)
