参考一下我的代码（其实是因为我没能力帮别人改代码）
```python
a=list(input())
c=0
for b in range(0,len(a)):
if a[b]=='.':
c=1
elif a[b]=='/':
c=2
elif a[b]=='%':
c=3
if c!=0:
d=a[:b][::-1]
if c!=3:
e=a[b+1:][::-1]
break
k=0
if c==0:
for f in a[::-1]:
if k!=0 or f!='0' or a==['0']:
print(f,end='')
if k==0:
k=1
elif c==1:
for g in d:
if k!=0 or g!='0' or d==['0']:
print(g,end='')
if k==0:
k=1
print('.',end='')
k=0
if e.count('0')==len(e):
e=['0']
else:
while e[-1]=='0':
del e[-1]
for h in e:
if k!=0 or h!='0' or e==['0']:
print(h,end='')
if k==0:
k=1
elif c==2:
for i in d:
if k!=0 or i!='0' or d==['0']:
print(i,end='')
if k==0:
k=1
print('/',end='')
k=0
for j in e:
if k!=0 or j!='0':
print(j,end='')
if k==0:
k=1
else:
for l in d:
if k!=0 or l!='0' or d==['0']:
print(l,end='')
if k==0:
k=1
print('%')
```
