Example 2: how to print a float with only 2 digits after decimal in python

#to round floats in Python you can use the "round" function. ex:

tax = 34.4563
tax = round(tax, 2)

#the number 2 at the end is how many digits are rounded.

#the variable "tax" would now be: 34.46

Example 3: round to two decimal places python

>>> x = 13.949999999999999999
>>> x
13.95
>>> g = float("{0:.2f}".format(x))
>>> g
13.95
>>> x == g
True
>>> h = round(x, 2)
>>> h
13.95
>>> x == h
True

Example 4: decimal in python

>>> from decimal import *
>>> getcontext().prec = 6
>>> Decimal(1) / Decimal(7)
Decimal('0.142857')
>>> getcontext().prec = 28
>>> Decimal(1) / Decimal(7)
Decimal('0.1428571428571428571428571429')

Example 5: give answer in 6 decimal python

print("{:.6f}".format(variable_name))

Example 6: print 2 decimal places python

print("{0:.2f}".format(sum(query_marks)/len(query_marks)))
