My Python 3.5.2 output in the terminal (on a mac) is limited to a width of ca. 80px, even if I increase the size of the terminal window.
This narrow width causes a bunch of line breaks when outputting long arrays which is really a hassle. How do I tell python to use the full command line window width?
For the record, i am not seeing this problem in any other program, for instance my c++ output looks just fine.
For numpy, it turns out you can enable the full output by setting
np.set_printoptions(suppress=True,linewidth=np.nan,threshold=np.nan).
ValueError: threshold must be numeric and non-NAN, try sys.maxsize for untruncated representation. However, numpy.set_printoptions(suppress=True,linewidth=numpy.nan) works!In Python 3.7 and above, you can use
from shutil import get_terminal_size
pd.set_option('display.width', get_terminal_size()[0])
pd from import pandas as pd? Why? The question does not mention pandas at all. Is it needed to solve the problem? BTW shutil.get_terminal_size() is exactly what I was searching for. --- Link to the documentation: docs.python.org/3/library/shutil.html#shutil.get_terminal_sizeI have the same problem while using pandas. So if this is what you are trying to solve, I fixed mine by doing
pd.set_option('display.width', pd.util.terminal.get_terminal_size()[0])
0.23.3. Fails with AttributeError: module 'pandas.util' has no attribute 'terminal'Default output of a 2x15 matrix is broken:
a.T
array([[ 0.2, -1.4, -0.8, 1.3, -1.5, -1.4, 0.6, -1.5, 0.4, -0.9, 0.3,
1.1, 0.5, -0.3, 1.1],
[ 1.3, -1.2, 1.6, -1.4, 0.9, -1.2, -1.9, 0.9, 1.8, -1.8, 1.7,
-1.3, 1.4, -1.7, -1.3]])
Output is fixed using numpy set_printoptions() command
import sys
np.set_printoptions(suppress=True,linewidth=sys.maxsize,threshold=sys.maxsize)
a.T
[[ 0.2 -1.4 -0.8 1.3 -1.5 -1.4 0.6 -1.5 0.4 -0.9 0.3 1.1 0.5 -0.3 1.1]
