请将 "hamming_decode" 函数定义后面的所有语句都移到第一个局部函数定义前面。

好的,以下是修改后的代码:
```python
def hamming_decode(bits):
# 定义局部函数
def parity_check(bits, parity):
return sum(bits[i] for i in range(len(bits)) if i & parity)
# 计算校验位
parity_bits = []
i = 0
while 2**i <= len(bits):
parity_bits.append(2**i - 1)
i += 1
# 进行纠错
error_index = 0
for parity in parity_bits:
bit = parity_check(bits, parity) % 2
if bit != 0:
error_index += parity
if error_index >= len(bits):
return "Error: No error correction possible"
bits[error_index] = 1 - bits[error_index]
# 计算原始数据
data = []
for i in range(len(bits)):
if i not in parity_bits:
data.append(bits[i])
return data
```
