- numpy. loadtxt( ) – Used to load text file data.
- numpy. genfromtxt( ) – Used to load data from a text file, with missing values handled as defined.

What is the rank of the NumPy array?
Rank of the array is the number of singular values of the array that are greater than tol. Input vector or stack of matrices. Threshold below which SVD values are considered zero. If tol is None, and S is an array with singular values for M, and eps is the epsilon value for datatype of S , then tol is set to S.
What is the rank of an array?
The rank of an array is the number of dimensions it has. A scalar is considered to have rank zero.
What is a rank 2 array?
The rank 2 array has 3 rows and 5 columns, so its shapes is (3, 5). By convention, we take the matrix shape to be rows first, then columns. The rank 3 array has 4 planes, each containing 3 rows and 5 columns, so its shapes is (4, 3, 5).
What is an array vs list?
An array is a method of organizing data in a memory device. A list is a data structure that supports several operations. An array is a collection of homogenous parts, while a list consists of heterogeneous elements.
