检查Python中的驼峰案例

Question

我想检查字符串是否是驼峰情况(布尔值).我倾向于使用正则表达式,但任何其他优雅的解决方案都可行.我写了一个简单的正则表达式

(?:[A-Z])(?:[a-z])+(?:[A-Z])(?:[a-z])+

这是正确的吗？或者我错过了什么？

我根据评论中的建议修改了我的正则表达式

(?:[A-Z])(?:\S?)+(?:[A-Z])(?:[a-z])+

Answer 1

您可以检查字符串是否包含大写和小写.

def is_camel_case(s):
    return s != s.lower() and s != s.upper() and "_" not in s


tests = [
    "camel",
    "camelCase",
    "CamelCase",
    "CAMELCASE",
    "camelcase",
    "Camelcase",
    "Case",
    "camel_case",
]

for test in tests:
    print(test, is_camel_case(test))

输出:python camel.py

camel False
camelCase True
CamelCase True
CAMELCASE False
camelcase False
Camelcase True
Case True
camel_case False
