>>> list(ast.literal_eval('(2,3,4),(1,6,7)'))
[(2, 3, 4), (1, 6, 7)]

字符串

不带ast或eval：

def convert(in_str):
    result = []
    current_tuple = []
    for token in in_str.split(","):
        number = int(token.replace("(","").replace(")", ""))
        current_tuple.append(number)
        if ")" in token:
           result.append(tuple(current_tuple))
           current_tuple = []
    return result

字符串

无AST：

>>> list(eval('(2,3,4),(1,6,7)'))
    [(2, 3, 4), (1, 6, 7)]

字符串

只是为了完整：soulcheck的解决方案，它满足了原始海报的要求，以避免ast.literal_eval：

def str2tupleList(s):
    return eval( "[%s]" % s )
