# Python: Find the maximum length of a substring of unique character in a given string

## Python Itertools: Exercise-24 with Solution

Write a Python program to find the maximum length of a substring in a given string where all the characters of the substring are the same. Use the itertools module to solve the problem.

Sample Solution:

Python Code:

``````import itertools

def max_sub_string(str1):
return max(len(list(x)) for _, x in itertools.groupby(str1))

str1 = "aaabbccddeeeee"

print("Original string:",str1)
print("Maximum length of a substring with unique characters of the said string:")
print(max_sub_string(str1))

str1 = "c++ exercises"
print("\nOriginal string:",str1)
print("Maximum length of a substring with unique characters of the said string:")
print(max_sub_string(str1))
```
```

Sample Output:

```Original string: aaabbccddeeeee
Maximum length of a substring with unique characters of the said string:
5

Original string: c++ exercises
Maximum length of a substring with unique characters of the said string:
2
```

## Python: Tips of the Day

Inverts a dictionary with non-unique hashable values:

Example:

```def tips_collect_dictionary(obj):
inv_obj = {}
for key, value in obj.items():
inv_obj.setdefault(value, list()).append(key)
return inv_obj
ages = {
"Owen": 25,
"Jhon": 25,
"Pepe": 15,
}
print(tips_collect_dictionary(ages))
```

Output:

```{25: ['Owen', 'Jhon'], 15: ['Pepe']}
```
