:[f][a][s][z][#][0][w][g][.p][t] can format a string with f-strings as shown below:
<Right-align a string with '>'>:
*It's like rjust().
v = "John Smith" print(f'"{v:>20}"') print(f'"{v: >20}"') # " John Smith" # ↑↑↑↑↑↑↑↑↑↑ print(f'"{v:?>20}"') # "??????????John Smith" print(f'"{v:?>17}"') # "???????John Smith" print(f'"{v:?>14}"') # "????John Smith" print(f'"{v:?>13}"') # "???John Smith" print(f'"{v:?>12}"') # "??John Smith" print(f'"{v:?>11}"') # "?John Smith" print(f'"{v:?>0}"') print(f'"{v:?>}"') print(f'"{v:>}"') print(f'"{v:}"') print(f'"{v}"') # "John Smith" v = " John Smith " # ↑↑↑ ↑↑↑ print(f'"{v:?>0}"') # " John Smith " # ↑↑↑ ↑↑↑ print(f'"{v:?>20}"') # "????

*It's like zfill().
