python打印空心长方形用*表示_用Python制作符合这些规范的空心盒？

我的解决方案：# Response to StackOverflow post:

# Making a hollow box in Python

# The multiplication operator (*) is the same as repeated

# concatenation when applied to strings in Python.

# I solved the problem by creating an array with N elements

# and gluing them together (str.join(array)) with newline

# characters.

# I trust you're already familiar with string formatting and

# concatenation, but in case you're not, please feel free to

# ask for clarification.

def main():

n = int (input("Enter an integer between 1 and 15"))

box = "n".join(["*"*(2*n)] + ["*%s*" % (" "*(2*n-2))]*(n-2) + ["*"*(int(n>1)*2*n)])

print (box)

if __name__ == '__main__':

main()

input() # Prevents the console from closing immediately

至于你的解决办法。在我看来，循环条件似乎混乱了；列循环和行循环的顺序相反，列循环中range()的参数应该是2*n(因为这是与每行相交的列数)。您还应该再次查看第一个print语句中的条件。
