In this lesson we have learned how to remove empty values from the array. We can remove the empty values from the string using array_filter() function
In some cases, we may want to remove only a specific number of zero values from the vector. Here, we remove the first two zeros. clc clear n=[102030];indices=find(n==0,2);n(indices)=[];n In this case, the second argument of thefind()function is utilized to limit the number of...
Remove Trailing Zeros From a String (strip, lstrip, rstrip) A string in Python is immutable – we cannot change it. However, we can convert it to list, remove the trailing zeros and convert it back to string using the join function. ...
