Python打印特殊字符

Question

在Python中如何打印特殊字符，如√，∞，²，³，≤，≥，±，≠

当我尝试将其打印到控制台时，我收到此错误：

print("√")

SyntaxError: Non-ASCII character '\xe2' in file /Users/williamfiset/Desktop/MathAid - Python/test.py on line 4, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

我该如何解决这个问题？

Answer 1

运行此代码会产生与您提供的SyntaxError相同的结果：

chars = ["√", "∞", "²","³", "≤", "≥", "±", "≠"]
for c in chars:
    print(c)

但如果我在脚本顶部添加# -*- coding: utf-8 -*-：

# -*- coding: utf-8 -*-

chars = ["√", "∞", "²","³", "≤", "≥", "±", "≠"]
for c in chars:
    print(c)

它会打印出来：

√
∞
²
³
≤
≥
±
≠

希望有所帮助。
