Loops in Python Python providesforandwhileloops for control flow statements. Python For Loop Theforloop iterates a sequence and executes the code inside the for loop once for each sequence. The following loop prints the value of “i” until it reaches 6. for i in range(6): print(i) Sim...

print([x for x in xyz if x in a]) 但是我在任何地方都找不到一个很好的例子(可以复制和学习)来演示一组复杂的命令(不仅仅是“打印 x”),这些命令在 for 循环和一些 if 语句的组合之后发生。我期望的东西看起来像: for x in xyz if x not in a: print(x...) 这不是 python 应该工作的方...
