是否可以表达使用Python简洁绘制的基于控制台的USA Flag？

Question

是否可以改善以下用python 2.7编写的代码？首先，请原谅我画错美国国旗的情况。这是我第一次进行python编程。我已经尽力了。顺便说一句，我画了5行带空间的星星，并在这些星和4行带空间少的星星之后画了两个额外的空间。然后，我绘制了其余的条纹。import sysfirst_time = Truesecond_time = Falsefirst_stars = 6second_stars = 5total_lines = 11stars1_col = 6stars2_col = 5total_tokens_per_line = 37first_total_lines = 24i = 0for i in range(total_lines):    if(first_time or second_time):        # if second_time is true print space at the beginning of every        # second line else just empty space        if(second_time):            sys.stdout.write(" ")        # else no space        else:            sys.stdout.write("")        # if first_time is true print a star and a space        if(first_time):            j = 0            for j in range(stars1_col):                sys.stdout.write("* ")            # first line is done reverse these two variables               second_time = True            first_time = False        # if not first_time print "* " and at the end of stars        # write space        else:            m = 0            for m in range(stars2_col):                sys.stdout.write("* ")            # write an extra space after every second line of stars            sys.stdout.write(" ")            # reverse these two variables again            first_time = True            second_time = False        # write an extra space after every second line of stars        sys.stdout.write(" ")        # draw the underscore lines (the stripes besides stars)        l = 0        for l in range(first_total_lines):            sys.stdout.write("_")        # now flush out or write stripes and stars besides stripes        sys.stdout.flush()        # if there are 8 lines printed print a newline        print("")        # if stars and stripes lines are total of 8 make these variables        # false        if (i == 8):            first_time = False            second_time = False此代码的输出是：

Answer 1

您还可以将列表理解与字符串连接一起使用。

print('\n'.join([''.join(['* '[(i + l) & 1] for i in range(11)]) + '  ' + '_' * 24 for l in range(9)] + ['_' * 37] * 3))

输出：
