Research
I conducted a test
I gave java to print to 10000000
I gave python to print to 10000000
Results Are Here:
Java Takes: "28.30" Seconds In 8GB RAM And i3 Processor
Python Takes: "04:25:85" Four Minute 25 Seconds & 85ms In 8GB RAM And i3 Processor

[@sudarshanmhaisdhune1039]

Cool!

[@anantgupta1188]

28 seconds lol

[@Bharatbaseltd]

Only in time computation though!

[@zohaib0335]

i think the time that you mentioned is the time that it takes to print these numbers in the command line rather than of computation. in computation they both would be really close.

[@garvitmaloo9538]

A note on the replace method - You can replace both - characters and strings. Use single quotes (' ') for characters and double quotes for string. Replace a character with a string and vice versa is not allowed. Like str.replace('c', "cc") is invalid.
