Adventures in Python: Printing Mathematical Symbols with Unicodes

Adventures in Python:  Printing Mathematical Symbols with Unicodes

Got to start somewhere.  I confess that I am a beginner when it comes to Python. 

With the use of the backslash, followed by a u, then four hexadecimal numbers, Python can print all sorts of symbols not easily found on a standard keyboard.  Some common math symbols and their Unicode:

039A
Δ
03C0
π
2202
2248
03A3
Σ
00B0
°
221A
2260
03A6
ϕ
0283
2264
221E
03C3
μ
03B4
δ
2265
03B8
θ
03BB
λ
2220
03B1
α
03B2
β
03C3
σ
0413
Γ
2205
29A8
2282
2283
221B
221D

A short program that demonstrates calling the Unicode characters:

# Program 001: Python Program
# Unicode is the format \uxxxx
# print command is used
print("This is some of my favorite constants (to 8 places).")
print("\u221A \u2248 1.41421356")
print("\u03C0 \u2248 3.14159265")
print("e \u2248 2.71828183")
print("\u03A6 \u2248 1.61803399")

Anything that comes after the hashtag (#) is a comment. 

Output:

This is some of my favorite constants (to 8 places).
√ ≈ 1.41421356
π ≈ 3.14159265
e ≈ 2.71828183
Φ ≈ 1.61803399
>>> 

Fairly simple.  Next up, I learn about input and the type of objects (the hard way).
