python list element from decimal into string -

-

i have 1 element in each list:

['39.95811864900048']

how can convert string. tried join:

"".join(item['longitude'])

it rounds off 2 decimals , returns

36.95

what need whole number string:

39.95811864900048

why not first element:

a = a[0]

example

>>> = ['39.95811864900048'] >>> = a[0] >>> '39.95811864900048'  >>> item['longitude'][0] '39.95811864900048'
