Prohibit automatic linebreaks in Pycharm Output when using large Matrices

Question

I\'m working in PyCharm on Windows. In the project I\'m currently working on I have \"large\" matrices, but when i output them Pycharm automatically adds linebreaks so that one

Answer 1

PyCharm default console width is set to 80 characters. Lines are printed without wrapping unless you set soft wrap in options: File -> Settings -> Editor -> General -> Console -> Use soft wraps in console.

However both options make reading big matrices hard. You can fix this in few ways.

With this test code:

import random
m = [[random.random() for a in range(10)] for b in range(10)]
print(m)

You can try one of these:

Pretty print

Use pprint module, and override line width:

import pprint
pprint.pprint(m, width=300)

Numpy

For numpy version 1.13 and lower:

If you use numpy module, configure arrayprint option:

import numpy
numpy.core.arrayprint._line_width = 300
print(numpy.matrix(m))

For numpy version 1.14 and above (thanks to @Alex Johnson):

import numpy
numpy.set_printoptions(linewidth=300)
print(numpy.matrix(m))

Pandas

If you use pandas module, configure display.width option:

import pandas
pandas.set_option('display.width', 300)
print(pandas.DataFrame(m))
