You’ll need tail. Some examples: $ tail great-big-file.log < Last 10 lines of great-big-file.log > If you really need to SKIP a particular number of “first” lines, use $ tail -n +<N+1> <filename> < filename, excluding first N lines. > That is, if you want to skip N lines, you start printing line N+1. Example: … Read more
>>> class Test: … def __repr__(self): … return “Test()” … def __str__(self): … return “member of Test” … >>> t = Test() >>> t Test() >>> print(t) member of Test The __str__ method is what gets called happens when you print it, and the __repr__ method is what happens when you use the repr() function … Read more
Update: Pandas 0.23.4 onwards This is not necessary. Pandas autodetects the size of your terminal window if you set pd.options.display.width = 0. (For older versions see at bottom.) pandas.set_printoptions(…) is deprecated. Instead, use pandas.set_option(optname, val), or equivalently pd.options.<opt.hierarchical.name> = val. Like: import pandas as pd pd.set_option(‘display.max_rows’, 500) pd.set_option(‘display.max_columns’, 500) pd.set_option(‘display.width’, 1000) Here is the help … Read more
In Python 3, print can take an optional flush argument: print(“Hello, World!”, flush=True) In Python 2, after calling print, do: import sys sys.stdout.flush() By default, print prints to sys.stdout (see the documentation for more about file objects).
I found this to be the only one short, flexible, portable and readable: # This line only if you still care about Python2 from __future__ import print_function import sys def eprint(*args, **kwargs): print(*args, file=sys.stderr, **kwargs) The optional function eprint saves some repetition. It can be used in the same way as the standard print function: … Read more
Since Java 5 you can use Arrays.toString(arr) or Arrays.deepToString(arr) for arrays within arrays. Note that the Object[] version calls .toString() on each object in the array. The output is even decorated in the exact way you’re asking. Examples: Simple Array: String[] array = new String[] {“John”, “Mary”, “Bob”}; System.out.println(Arrays.toString(array)); Output: [John, Mary, Bob] Nested Array: … Read more
