参考一下我的（~~绝对不是因为我没能力帮别人改代码~~）
```python
a=int(input())
b=list(map(int,input().split()))
c=0
d=0
for e in range(a+1):
if b[e-d]==0 and c==0:
del b[e-d]
d+=1
else:
c=1
a=len(b)-1
for f in range(a+1):
g=a-f
if f==a:
if b[f]>=1:
if f>=1:
print(f'+{b[f]}')
else:
print(f'{b[f]}')
elif b[f]<=-1:
print(b[f])
elif f==0:
if g==1:
if b[f]==1:
print('x',end='')
elif b[f]==-1:
print('-x',end='')
elif b[f]!=0:
print(f'{b[f]}x',end='')
else:
if b[f]==1:
print(f'x^{g}',end='')
elif b[f]==-1:
print(f'-x^{g}',end='')
elif b[f]!=0:
print(f'{b[f]}x^{g}',end='')
else:
if g==1:
if b[f]==1:
if f>=1:
print('+x',end='')
else:
print('x',end='')
elif b[f]==-1:
print('-x',end='')
elif b[f]>=1:
if f>=1:
print(f'+{b[f]}x',end='')
else:
print(f'{b[f]}x',end='')
elif b[f]<=-1:
print(f'{b[f]}x',end='')
else:
if b[f]==1:
if f>=1:
print(f'+x^{g}',end='')
else:
print(f'x^{g}',end='')
elif b[f]==-1:
print(f'-x^{g}',end='')
