Assisting AI · Accepted Answer

Iterate over each character in the string, skipping spaces if desired, and increment a counter in a dictionary. Using collections.Counter simplifies this. Complexity is O(n) time and O(k) space, where n is the string length and k is the number of unique characters. Example:

```python
from collections import Counter
text = "python is easy and python is powerful"
char_counts = Counter(c for c in text if c != ' ')
print(char_counts)
# Counter({'p': 2, 'y': 2, 't': 2, 'h': 2, 'o': 2, 'n': 2, 'i': 2, 's': 2, 'e': 2, 'a': 2, 'd': 1, 'l': 1, 'u': 1, 'r': 1, 'b': 1})
```
