### What is the meaning of reshape (- 1 1?

– Jalli Artturi. The reshape() function in NumPy calculates an unknown dimension for you when you specify -1 in the reshape(-1) command. It’s equivalent to saying: Let the reshape() function decide how to handle this dimension. Flattening an unknown-element nested array to a 1D array is a frequent use case.

### When we use reshape in Python?

– An array can be given a new shape with the help of the reshape() function without having its data changed. array that will be modified. The modified shape must be compatible with the original. If the input is an integer, a 1-D array with that length will be the outcome.

### How can we apply a reshape () in array?

– We use the reshape method with the supplied array to reshape a numpy array. array is the syntax. reshape(shape)Argument: It accepts a tuple as an argument, which is the new shape that is to be created. Return: Numpy is returned. ndarray.

## Additional Question How do you reshape in Python?

### What is a reshape mean?

– Reshape transitive verb definition. Reorganize means to give something a new form or orientation.

### What does reshape mean in Python?

– In Python, we can reshape an array using the reshape() function. Changing an array’s shape is the essence of reshaping. The quantity of elements in each dimension also affects an array’s shape. We can add or remove dimensions from an array by reshaping.

### How do you reshape an array to 2D?

– Let’s use this to convert our 1D numpy array to 2D numpy array,arr = np. array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])# Convert 1D array to a 2D numpy array of 2 rows and 3 columns.arr_2d = np. reshape(arr, (2, 5))print(arr_2d)

### How do you reshape a data frame?

– To change a pandas DataFrame from wide to long format, use the following simple syntax: df = pd. In this case, col1 is the column we use as an identifier and col2, col3, etc. are the value variables.

### How do you reshape an image array in Python?

– As mentioned in the section above, flattening an array with np is one of the additional ways to reshape a numpy array. function used by ravel After that, feed np with the output of the ravel function. the new shape for the final output array array and the reshape() function.

### How do you reshape a NumPy array in one direction?

– A multidimensional array is flattened when it is reduced to a single dimension (1D array). To accomplish this, use reshape(-1).

## Conclusion :
