python format 2 digits

number = 1

# In Python 2 (and Python 3) you can do:
print("%02d" % (number,))
# Basically % is like printf or sprintf (see docs).

# For Python 3.+, the same behavior can also be achieved with format:
print("{:02d}".format(number))

# For Python 3.6+ the same behavior can be achieved with f-strings:
print(f"{number:02d}")
