continue语句被用来告诉Python跳过当前循环块中的剩余语句,然后 继续 进行下一轮循环。 for for..in是另外一个循环语句,它在一序列的对象上 递归 即逐一使用队列中的每个项目 lambda 匿名函数是个很时髦的概念,提升了代码的简洁程度。如: g=lambda x:x*2g(3) 1. 2. try 我们可以使用try..except语句来处理异...
# for 循环 for i in range(5): if i == 3: continue # 跳过 3 print(i) # while 循环 count = 0 while count < 5: if count == 2: break # 提前终止循环 print(count) count += 1 ✅ break 终止循环,continue 跳过当前循环,pass 作为占位符。 5. 异常处理关键字:try, except, finally,...

Python is a case-sensitive language. This means, Variable and variable are not the same. Always give the identifiers a name that makes sense. While c = 10 is a valid name, writing count = 10 would make more sense, and it would be easier to figure out what it represents when you look...
