标签：测试 locate dsc 字典 array statement with var line
要遍历一个范围(如数组或表)，使用 for 循环。在数组上迭代时，当前数组元素存储在循环变量中。在遍历字典时， index 存储在循环变量中。
(in 内容测试)
for x in [5, 7, 11]:
statement # Loop iterates 3 times with ‘x‘ as 5, then 7 and finally 11.
var dict = {"a": 0, "b": 1, "c": 2}
for i in dict:
print(dict[i])
for i in range(3):
statement # Similar to [0, 1, 2] but does not allocate an array.
for i in range(1,3):
statement # Similar to [1, 2] but does not allocate an array.
for i in range(2,8,2):
statement # Similar to [2, 4, 6] but does not allocate an array.
for c in "Hello":
print(c) # Iterate through all characters in a String, print every letter on new line.
