if c.isupper():
d["UPPER_CASE"]+=1
elif c.islower():
d["LOWER_CASE"]+=1
else:
pass
print ("Original String : ", s)
print ("No. of Upper case characters : ", d["UPPER_CASE"])
print ("No. of Lower case Characters : ", d["LOWER_CASE"])

return s[:1].lower() + (s[1:].upper() if upper_rest else s[1:])
print(tips_decapitalize('PythonTips'))
print(tips_decapitalize('PythonTips', True))
```

Output:

```pythonTips
pYTHONTIPS
