What will be the output of the following Python functions? float('1e-003') float('2e+003')

Answer: Option B

Option B: 0.001
2000.0
When the strings '1e-003' and '2e+003' are passed to the float() function, they are interpreted as scientific notation representing floating-point numbers.

'1e-003' represents 1×10⁻³ which is equal to 0.001.
'2e+003' represents 2×10³ which is equal to 2000.0.

Therefore, the output will be 0.001 and 2000.0.
