numpy File IO with numpy Loading numerical data from text files with consistent structure
Example
The function np.loadtxt can be used to read csv-like files:
# File:
# # Col_1 Col_2
# 1, 1
# 2, 4
# 3, 9
np.loadtxt('/path/to/dir/csvlike.txt', delimiter=',', comments='#')
# Output:
# array([[ 1., 1.],
# [ 2., 4.],
# [ 3., 9.]])
The same file could be read using a regular expression with np.fromregex:
np.fromregex('/path/to/dir/csvlike.txt', r'(\d+),\s(\d+)', np.int64)
# Output:
# array([[1, 1],
# [2, 4],
# [3, 9]])
