Returns a view of the array with axes transposed. For a 1-D array this has no effect, as a transposed vector is simply the same vector. To convert a 1-D array into a 2D column vector, an additional dimension must be added. np.atleast2d(a).T achieves this, as does a[:, np.newaxis]. For a 2-D array, this is a standard matrix transpose. For an n-D array, if axes are given, their order indicates how the axes are permuted (see Examples).

If axes are not provided and a.shape = (i[0], i[1], ... i[n-2], i[n-1]), then a.transpose().shape = (i[n-1], i[n-2], ... i[1], i[0]). None or no argument: reverses the order of the axes. tuple of ints: i in the j-th place in the tuple means a’s i-th axis becomes a.transpose()’s j-th axis. n ints: same as an n-tuple of the same ints (this form is intended simply as a “convenience” alternative to the tuple form)

The ndarray.transpose() function returns a view of the array with axes transposed. Return : [ndarray] View of arr, with axes suitably permuted. Let's look at some examples to of transpose() method of the NumPy library to find transpose of a ndarray: NumPy, short for Numerical Python, is an essential library in the Python data science ecosystem. It provides support for large, multi-dimensional arrays and matrices, along with a collection of mathematical functions to perform operations on these arrays. One such powerful operation is the ndarray.transpose() method, which rearranges the dimensions of an array.

In this tutorial, we’ll demystify the workings of transpose() through illustrative examples, spanning from basic to advanced use cases. To start with the basics, let’s consider a simple 2D array. Transposing this array essentially swaps its rows with its columns. Moving ahead to slightly more complex structures, let’s consider transposing a 3-dimensional array. Here, we have more flexibility in how we want to rearrange the dimensions. For a more in-depth manipulation, transpose() allows for the specification of axes to define exactly how the dimensions should be swapped.

This ability is particularly useful for higher-dimensional data manipulation. Transposing arrays plays a crucial role in data analysis and preprocessing. Let’s go through an advanced example where we utilize transposition within a data processing context. To transpose NumPy array ndarray (swap rows and columns), use the T attribute (.T), the ndarray method transpose() and the numpy.transpose() function. With ndarray.transpose() and numpy.transpose(), you can not only transpose a 2D array (matrix) but also rearrange the axes of a multi-dimensional array in any order. This article describes the following contents.

If you want to swap rows and columns of pandas.DataFrame or a two-dimensional list (list of lists), see the following article. You can get the transposed matrix of the original two-dimensional array (matrix) with the T attribute. Returns a view of the array with axes transposed. For a 1-D array this has no effect, as a transposed vector is simply the same vector. To convert a 1-D array into a 2D column vector, an additional dimension must be added. np.atleast2d(a).T achieves this, as does a[:, np.newaxis].

For a 2-D array, this is a standard matrix transpose. For an n-D array, if axes are given, their order indicates how the axes are permuted (see Examples). If axes are not provided and a.shape = (i[0], i[1], ... i[n-2], i[n-1]), then a.transpose().shape = (i[n-1], i[n-2], ... i[1], i[0]). Array property returning the array transposed.

Give a new shape to an array without changing its data. © 2005–2021 NumPy DevelopersLicensed under the 3-clause BSD License. https://numpy.org/doc/1.21/reference/generated/numpy.ndarray.transpose.html Returns a view of the array with axes transposed. Refer to numpy.transpose for full documentation. None or no argument: reverses the order of the axes.

tuple of ints: i in the j-th place in the tuple means that the array’s i-th axis becomes the transposed array’s j-th axis. n ints: same as an n-tuple of the same ints (this form is intended simply as a “convenience” alternative to the tuple form). An array object represents a multidimensional, homogeneous array of fixed-size items. An associated data-type object describes the format of each element in the array (its byte-order, how many bytes it occupies in memory, whether it is an integer, a floating point number, or something else,... Arrays should be constructed using array, zeros or empty (refer to the See Also section below). The parameters given here refer to a low-level method (ndarray(…)) for instantiating an array.

For more information, refer to the numpy module and examine the methods and attributes of an array. Any object that can be interpreted as a numpy data type. Row-major (C-style) or column-major (Fortran-style) order. With the help of Numpy numpy.transpose(), We can perform the simple function of transpose within one line by using numpy.transpose() method of Numpy. It can transpose the 2-D arrays on the other hand it has no effect on 1-D arrays. This method transpose the 2-D numpy array.

Parameters: axes : [None, tuple of ints, or n ints] If anyone wants to pass the parameter then you can but it's not all required. But if you want than remember only pass (0, 1) or (1, 0). Like we have array of shape (2, 3) to change it (3, 2) you should pass (1, 0) where 1 as 3 and 0 as 2.Returns: ndarray Example #1 : In this example we can see that it's really easy to transpose an array with just one line. Example #2 : In this example we demonstrate the use of tuples in numpy.transpose().
