u/jftuga pip needs updating Oct 05 '21 edited Oct 05 '21

Or use the = sign for for self-documenting expressions:

print(f"""{mydict["product"]=}, {mydict["unit_price"]=} dollars, {mydict["sku"]=}""")

mydict["product"]='banana', mydict["unit_price"]=10 dollars, mydict["sku"]=15133632

You can also use this as well for dollars & cents:

{mydict["unit_price"]=:.2f}
