I'm getting back into Python after a multi-year hiatus, and I need some help with the f-strings everyone's been using. Last I checked, str.format() was the way to do it. Can you give me an example of the difference between using f-strings and str.format()?

main bahu-varsh ke antaraal ke baad paythan main waapas aa rahaa hum, or mujhe epa-strings ke saath kuch madad kii zarurat he jo sabhi kaa upyog kar rahe hai.antim maine jaanch kii, str.format () ise karne kaa tarika tha.kya aap mujhe epa-strings or str.format () kaa upyog karne ke bich antar kaa ek udhaaharan de sakate hai?

paythan 3.6 ne swaroopit string shabdic, yaa epa-strings pesh kiya, jo aapako shuruyaat main "epa" ke saath string se pehle ghunghraale bracis ke andar ek string main sidhe char ko ambed karne kii anumati detaa he.yah str.format () vidhi se alag he jisamen placeolder ghunghraale bracis shaamil hai or string ke ant main ek .Format () vidhi main char ko nirdisht karata he.

yahan do tareekon kii tulana main ek udhaaharan diya gaya he:

naam = "sam"
pesha = "programmer"
bhashaa = "paythan"

# str.format () vidhi udhaaharan
print (("{} ek {} he jo {} bhashaa main maahir he."). praaroop (naam, peshey, bhashaa))

# epa-string vidhi udhaaharan
print (f "{naam} ek {pesha} he jo {bhashaa} bhashaa main maahir he.")

ye donon output honge, "sam ek programmer he jo paythan bhashaa main maahir he."jaisaa ki aap dekh sakate hai, epa-string vidhi aamtaur par str.format () vidhi kii tulana main adhik sankshipt or pathneey he.
