将科学计数法字符串转换为int

Question

How would I convert:

s='8.833167174e+11' (str)
==> 883316717400 (int)

I tried doing int(s) or some other 'casting' but it wasn't effective.

Answer 1

As your string is a float digit you need to first convert it to float :

>>> int(float(s))
883316717400

float([x])

Return a floating point number constructed from a number or string x.

If the argument is a string, it must contain a possibly signed decimal or floating point number, possibly embedded in whitespace. The argument may also be [+|-]nan or [+|-]inf. Otherwise, the argument may be a plain or long integer or a floating point number, and a floating point number with the same value (within Python's floating point precision) is returned. If no argument is given, returns 0.0.
