Simpmle common utilities.
pip install mbmutils
The f
-functions are simple string utilities of common actions. They have the
standard pattern of:
return string after|before|between the keys
These all use the "first found" index. Meaning if there are more than one
instance of the key found, they use the first. Because of this there are functions
that look from the front (f_left | f_right
) and functions that look from the
back (f_left_back | f_right_back
).
function | Description |
---|---|
f_right | return everything to the right of the key |
f_left | return everything to the left of the key |
f_right_back | return everything to the right of the key, starting from the back |
f_left_back | return everything to the left of the key, starting from the back |
f_between | return everything between the keys |
You will also find a not_found
parameter to these functions. This
allows you to define what is returned if the key is not found in the string.
from mbmutils import mu
my_string = "hello there fancy world!"
print({mu.f_right(my_string, ' fancy ')})
# -> world!
print({mu.f_left(my_string, ' fancy ')})
# -> hello there
print({mu.f_left(my_string, 'will not find')})
# -> None
print({mu.f_left(my_string, 'will not find',
not_found="not here")})
# -> not here
There are also a few path-finding functions that search for a path
containing the partial_path
provided. These will search the current path
and then begin looking upward from there.
There are 2 functions: 1 for files and the other for directories.
from mbmutils import mu
# assuming current folder is
# /path/to/python/code
mu.find_folder_path('data')
# will return the first valid:
# -> path/to/python/code/data
# -> path/to/python/data
# -> path/to/data
# -> path/data
# again, assuming current folder is
# /path/to/python/code
mu.find_folder_path('my_file.json')
# will return the first valid:
# -> path/to/python/code/my_file.json
# -> path/to/python/my_file.json
# -> path/to/my_file.json
# -> path/my_file.json
