Mastering Element Replacement in NumPy Arrays
The second method involves replacing elements in a NumPy array that satisfy one condition This can be done using NumPy s where function but this time with only one array input Here s an example of how to replace all positive elements in a NumPy array with 1 python import numpy as np arr np array 2 3 5 1 10 7 0 20
Numpy place NumPy v1 26 Manual, 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 Parameters arrndarray

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 Method 1 Using Relational operators Example 1 In 1 D Numpy array Python3 import numpy as np n arr np array 75 42436315 42 48558583 60 32924763 print Given array print n arr print nReplace all elements of array which are greater than 50 to 15 50 n arr n arr 50 15 50 print New array n print n arr Output
