How do I convert a string to a double in Python?

python string double

>>> x = "2342.34">>> float(x)2342.3400000000001

There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).

The decimal operator might be more in line with what you are looking for:

>>> from decimal import Decimal>>> x = "234243.434">>> print Decimal(x)234243.434

Be aware that if your string number contains more than 15 significant digits float(s) will round it.In those cases it is better to use Decimal
