The len() returns the length of the string. We add trailing zeros to the string by manipulating the length of the given string and the ljust function.
How do I print more significant digits in Python?
The “g” format specifier is a general format that can be used to indicate a precision, or to indicate significant digits. To print a number with a specific number of significant digits we do this: print ‘{0:1.3g}’. format(1./3.)
How do you keep zero when rounding in Python?
- No need for the round call: the .
- %.2f already does the rounding for you, so you can also use: “%.2f” % (2606.89579999999) or format(2606.89579999999, ‘.2f’)
