python decimal places code example
Example 1: python 2 decimal places
print(format(432.456, ".2f"))
>> 432.45
print(format(321,".2f"))
>> 321.00
Example 2: 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 3: 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 4: fixed precision float python
x = 13.949999999999999999
g = float("{:.2f}".format(x))
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)))
