SymPy can pretty print the output using ASCII and Unicode characters. There are a number of printers available in SymPy. The following are the most common printers of SymPy:
LaTeX
MathML
Unicode pretty printer
ASCII pretty printer
Str
dot
repr
This program demonstrates the pretty print function to print various expressions using the ASCII and Unicode printers:
from sympy.interactive import init_printing
from sympy import Symbol, sqrt
from sympy.abc import x, y
sqrt(21)
init_printing(pretty_print=True)
sqrt(21)
theta = Symbol('theta')
init_printing(use_unicode=True)
theta
init_printing(use_unicode=False)
theta
init_printing(order='lex')
str(2*y + 3*x + 2*y**2 + x**2+1)
init_printing(order='grlex')
str(2*y + 3*x + 2*y**2 + x**2+1)
init_printing(order='grevlex')
str(2*y * x**2 + 3*x * y**2)
init_printing(order='old')
str(2*y + 3*x + 2*y**2 + x**2+1)
init_printing(num_columns=10)
str(2*y + 3*x + 2*y**2 + x**2+1)The following program uses the LaTeX printer for pretty printing...
