How do i type a symbol in python?
Unicode characters are very useful for engineers. A couple commonly used symbols in engineers include Omega and Delta. We can print these in python using unicode characters. From the Python interpreter we can type: Show >>> print('Omega: \u03A9') Omega: Ω >>> print('Delta: \u0394') Delta: Δ >>> print('sigma: \u03C3') sigma: σ >>> print('mu: \u03BC') mu: μ >>> print('epsilon: \u03B5') epsilon: ε >>> print('degree: \u00B0') degree: ° >>> print('6i\u0302 + 4j\u0302-2k\u0302') 6î + 4ĵ-2k̂ All of these are unicode characters. Python has support for unicode characters built in. You can check if your system supports it by importing the >>> import sys >>> sys.getdefaulencoding() 'utf-8' If you see There are a couple of special characters that will combine symbols.
