Convert a plane string to date format in Python

Question

I have a plane text like '20211111012030' and need to convert it to 'YYYY-MM-DD HH:MM:SS'(2021-11-11 01:20:30) format in python .How can I convert it to a specific format as above

Answer 1

Use the datetime package.

from datetime import datetime

dt_str = '20211111012030'
dt = datetime.strptime(dt_str, '%Y%m%d%H%M%S')
print(dt)

Answer 2

You could use a regex approach:

inp = '20211111012030'
output = re.sub(r'(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})', r'\1-\2-\3 \4:\5:\5', inp)
print(output)  # 2021-11-11 01:20:20
