How to Replace Elements in NumPy Array 3 Examples , Method 2 Replace Elements Based on One Condition The following code shows how to replace all elements in the NumPy array greater than 8 with a new value of 20 replace all elements greater than 8 with 20 my array my array 8 20 view updated array print my array 4 5 5 7 8 8 20 20
Numpy place NumPy v1 26 Manual
Numpy place numpy place arr mask vals source Change elements of an array based on conditional and input values Similar to np copyto arr vals where mask the difference is that place uses the first N elements of vals where N is the number of True values in mask while copyto uses the elements where mask is True Note that extract does the exact opposite of place
Numpy where Manipulate elements depending on conditions, Numpy where condition x y Return elements either from x or y depending on condition If only condition is given return condition nonzero numpy where NumPy v1 14 Manual np where is a function that returns ndarray which is x if condition is True and y if False x y and condition need to be broadcastable to same shape

1 NumPy replace value in Python To replace a value in NumPy array by index in Python assign a new value to the desired index For instance import numpy as np temperatures np array 58 66 52 69 77 temperatures 0 59 print Updated Temperatures temperatures Output Updated Temperatures 59 66 52 69 77 How to replace values in NumPy array by index in Python 4 Ways . NumPy Replace Values With the numpy clip Function If we need to replace all the greater values than a certain threshold in a NumPy array we can use the numpy clip function We can specify the upper and the lower limits of an array using the numpy clip function The numpy clip function returns an array where the elements less than the specified limit are replaced with the lowest limit How to replace elements based on condition in Numpy in Python Replace all elements which are greater than 30 to 0 import numpy as np the array np array 49 7 44 27 13 35 71 an array np where the array 30 0 the array print an array
