 ### General Options
 ```python

-{<el>:>10}       # '      <el>'
-{<el>:^10}       # '   <el>   '

+f'{<el>:->10}'      # '------<el>'

 ```
 
 ### String Options
 **`'!r'` calls object's repr() method, instead of format(), to get a string.**
 ```python
-{'abcde'!r:<10}  # "'abcde'   "
-{'abcde':.3}     # 'abc'
-{'abcde':10.3}   # 'abc       '
+f'{'abcde'!r:<10}'  # "'abcde'   "
+f'{'abcde':.3}'     # 'abc'
+f'{'abcde':10.3}'   # 'abc       '
 ```
 
 ### Number Options
 ```python
-{ 123456:10,}    # '   123,456'
-{ 123456:10_}    # '   123_456'
-{ 123456:+10}    # '   +123456'
-{-123456:=10}    # '-   123456'
-{ 123456: }      # ' 123456'
-{-123456: }      # '-123456'
+f'{ 123456:10,}'    # '   123,456'
