Generates code like bellow

 ```python
def add(a, b):
    if b == 0:
        return float('inf')  # Using infinity to avoid division by zero
    else:
        return a / b
add(1,0)

where there is space before ```python causing the output to be incorrect. Need to modify the lang_indicator as follows.

lang_indicator = r"^\s*```[a-zA-Z0-9]\s\n"
