Question
In the expression x = y + x, where y is a floating-point variable and x is an integer variable. What happens if we print x as an integer?
Solution
In the expression x = y + x, the y is a floating-point variable and x is an integer variable. When these two different types of variables are added together, Python will automatically convert the integer x to a floating-point number before performing the addition. This is called type coercion.
So, the result of y + x will be a floating-point number. This result is then assigned to x. Now, x is no longer an integer, but a floating-point number.
If we print x as an integer using print(int(x)), Python will convert the floating-point x to an integer. This conversion is done by truncating the decimal part of the floating-point number, not by rounding. For example, if x is 3.7, print(int(x)) will print 3.
However, if you print x without converting it to an integer using print(x), it will print the floating-point number. For example, if x is 3.7, print(x) will print 3.7.
