Answer 1

import re

def get_pascal_case(input_str):
    if ' ' not in input_str:
        input_str = re.sub(r'(?<=[a-z])(?=[A-Z])', ' ', input_str)
    
    words = input_str.lower().split()
    result = ''.join(word.capitalize() for word in words)
    
    return result.replace('_', '')
    

print(get_pascal_case("get file content"))
print(get_pascal_case("get_file_content"))
print(get_pascal_case("get______file___content"))
print(get_pascal_case("get______file____  content"))
print(get_pascal_case("GET FILE CONTENT"))
print(get_pascal_case("get    file      content"))
