Numpy's trim_zeros() method returns a new Numpy array with the leading (front) and trailing (back) zeros removed.

Parameters

1. a | array-like

An one-dimensional array.

2. trimlink | string | optional

Whether to trim only the leading, trailing or both leading and trailing zeros:

Value	Meaning
"f"	Trims the front zeros.
"b"	Trims the zeros at the back.
"fb"	Trim both the front and the back zeros.

By default, trim="fb".

Return value

A new Numpy array with the leading and trailing zeros removed.

Examples

Trimming both leading and trailing zeros


        
        
            
                
                
                    a = np.array([0,4,5,0,0])
np.trim_zeros(a)
                
            
            array([4, 5])

Trimming only the leading zeros


        
        
            
                
                
                    a = np.array([0,4,5,0,0])
np.trim_zeros(a, trim="f")
                
            
            array([4, 5, 0, 0])

Trimming only trailing zeros


        
        
            
                
                
                    a = np.array([0,4,5,0,0])
np.trim_zeros(a, trim="b")
                
            
            array([0, 4, 5])
