You can do this with str.ljust(width[, fillchar]):
Return the string left justified in a string of length width. Padding is done using the specified fillchar (default is a space). The original string is returned if width is less than
len(s).
>>> 'hi'.ljust(10)
'hi '

For a flexible method that works even when formatting complicated string, you probably should use the string-formatting mini-language,
using either f-strings
>>> f'{"Hi": <16} StackOverflow!' # Python >= 3.6
'Hi StackOverflow!'
or the str.format() method
>>> '{0: <16} StackOverflow!'.format('Hi') # Python >=2.6
'Hi StackOverflow!'

Padding Strings in Python
September 18, 2023 - To combat this, we could write for/while loops and append spaces to the strings until they reached a certain length, and make sure that all the data is aligned properly for easy visual inspection. Or, we could use built-in functions that can achieve the same goal. The functions we'll be taking a look at in this article are: ljust(), center(), rjust(), zfill() and format().

As maybe a alternative more portable [1] and efficient [2], actually you can just use str.ljust.
In [2]: '190'.ljust(8, '0')
Out[2]: '19000000'
In [3]: str.ljust?
Docstring:
S.ljust(width[, fillchar]) -> str
Return S left-justified in a Unicode string of length width. Padding is
done using the specified fill character (default is a space).

[1] format is not present on old python versions. format specifier was added since Python 3.0 (see PEP 3101) and Python 2.6.

See Format Specification Mini-Language:
In [1]: '{:<08d}'.format(190)
Out[1]: '19000000'
In [2]: '{:>08d}'.format(190)
Out[2]: '00000190'
This also works with the Formatted String Literals, or f-strings for short (New in version 3.6):
In [1]: f'{190:<08d}'
Out[1]: '19000000'
In [2]: f'{190:>08d}'
