how to calculate the number of fields in the smali file?

Question

Need to calculate the number of methods and variables in the smali file, not through dex. How?

It's better to use Python language, please

I simply calculated the number of .field in the smali file and found a significant difference from the actual system calculation.

def parse_smali_method_num(smali_path):
    count = 0
    with open(smali_path, 'r', 4096, 'utf-8') as f:
        text = f.readline()
        if (not text.startswith('.class')):
            print('Warning:Not a class smali file:' + str(smali_path))
            return 0
        while (text):
            text = f.readline()
            if (text.startswith('.method')):
                count += 1
    return count

def parse_smali_field_num(smali_path):
    count = 0
    with open(smali_path, 'r', 4096, 'utf-8') as f:
        text = f.readline()
        if (not text.startswith('.class')):
            print('Warning:Not a class smali file:' + str(smali_path))
            return 0
        while (text):
            text = f.readline()
            if (text.startswith('.field')):
                count += 1
    return count
