I have a list
a = [49, 51, 53, 56] How do I subtract 13 from each integer value in the list?

To subtract two numbers in Python, use the subtraction(-) operator. The subtraction operator (-) takes two operands, the first operand on the left and the second operand on the right, and returns the difference of the second operand from the first operand.
subtract() function is used when we want to compute the difference of two array.It returns the difference of arr1 and arr2, element-wise. Parameters : arr1 : [array_like or scalar]1st Input array. arr2 : [array_like or scalar]2nd Input array.
With a list comprehension:
a = [x - 13 for x in a] If are you working with numbers a lot, you might want to take a look at NumPy. It lets you perform all kinds of operation directly on numerical arrays. For example:
>>> import numpy >>> array = numpy.array([49, 51, 53, 56]) >>> array - 13 array([36, 38, 40, 43]) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
