Question

what is the output of the following code?

x = \7\
y = float(x) + 3.5
print(y)

10.5
73.5
10
error

Explanation:

Step1: Convert string to float

The float(x) function converts the string "7" to the float value \(7.0\).

Step2: Perform addition

We calculate \(7.0+3.5\). Using the formula for addition of two float numbers \(a + b\) where \(a = 7.0\) and \(b=3.5\), we get \(7.0+3.5=10.5\).

Answer:

10.5
