python - 类型错误 : unsupported operand type(s) for +: 'float' and 'tuple'

Question

我有这个元组:

results[0]

#0 tuple(7) 
    [0] => int(375851) 
    [1] => str(26) "joaquina gisela dos sanots"
    [2] => str(10) "1963-11-24"
    [3] => int(378129) 
    [4] => str(26) "Joaquina Gisela Dos Santos"
    [5] => str(10) "1963-11-24"
    [6] => float(1.0) 

我想将这个 float 添加到索引 0:

lev_name = float(0.92) 

预期输出:

#0 tuple(8) 
    [0] => float(0.92) 
    [1] => int(375851) 
    [2] => str(26) "joaquina gisela dos sanots"
    [3] => str(10) "1963-11-24"
    [4] => int(378129) 
    [5] => str(26) "Joaquina Gisela Dos Santos"
    [6] => str(10) "1963-11-24"
    [7] => float(1.0) 

我正在尝试:

results = lev_name + results[0] 

我该怎么做？

Answer 1

试试这个

results = (lev_name,) + results

你不能添加到索引 0. 因为元组是不可变的.. :)
