I understand you are talking about the 'while' loop in Python. The loop is enabled while something is true. Hence, it is called 'while'. Here is an example. num = 6 while num > 0: num -= 1 if num == 2: break print(num) We create a variable num and set its value to 6. ...
while的代码test1.py: i = 0 while i < 10000000: i += 1 for-loop的代码test2.py: for n in range(0,10000000):...pass time python test1.py 或者test2.py,得到第一个的时间大概是0m1.189s;第二个的时间是0m0.514s。...while循环的时间大概是for-range的两倍。 其实如果对python字节码的...

打开windows命令行输入cmd,确定后 写入代码python d:t1.py 您已经运行了第一个python程序, 即:终端--->cmd---> python 文件路径。 回车搞定~ 2,解释器。 上一步中执行 python d:t1.py 时,明确的指出 t1.py 脚本由 python 解释器来执行。 如果想要类似于执行shell脚本一样执行python脚本,例:./t1.py,那么...
In Python, the expression while(1): doesn't directly translate as it does in some other programming languages like C or C++. However, I can explain what a similar concept means in Python. In languages like C, while(1); creates an infinite loop because 1 is always true in a boolean co...

You should run the loop in a separate thread. However to access controls on the Form from a separate thread you will need to use something such as a delegate sub to update those controls as the delegate sub will be on the same thread as the Form....
