尝试遍历以下输出python

string = "python"
for char in string:
    print(char)

string = "python"
for i in range(len(string)):
    print(string[i])

string = "python"
for index, char in enumerate(string):
    print(index, char)

string = "python"
characters = [char for char in string]
for char in characters:
    print(char)
