You also practiced capturinginputfrom a user as a string using theinput()function, and you converted that input to a number usingint()andfloat(). You converted numbers and other objects to strings usingstr(). Finally, you used the.find()and.replace()methods to find the location of a sub...
When you pass these values to an f-string or the .format() method, the g presentation type produces lowercase output, and G produces uppercase output:Python >>> infinite = float("inf") >>> infinite inf >>> not_a_number = infinite * 0 >>> not_a_number nan >>> f"{infinite:g...
Method 2: Rounding Methods Sometimes simply truncating a float isn’t what you want. Python offers several ways to round numbers before converting them to integers. Use round() Function float_number = 7.85 rounded_number = round(float_number) ...
