在循环中使用end=parameter(Python)

打印任何想要的输出而不使用换行符的最直接的方法是使用 sys.stdout.write stdout 不添加新行。

>>> import sys
>>> sys.stdout.write("foo")
foo>>> sys.stdout.flush()
>>> 

如上图所示, "foo" 没有换行。

end 参数乘以哈希数,而不是乘以主文本部分。

尝试此修改:

length = int(input("Enter size of pyramid."))
hashes = 2
for i in range(0, length):
    spaces = length - (i+1)
    hashes = 2+i
    print(" " * spaces, end="")
    print("#" * hashes, end="")
    print("  ", end="")
    print("#" * hashes)

尝试此算法:

length = int(input("Enter size of pyramid."))
# Build left side, then rotate and print all in one line
for i in range(0, length):
    spaces = [" "] * (length - i - 1)
    hashes = ["#"] * (1 + i)
    builder = spaces + hashes + [" "]
    line = ''.join(builder) + ''.join(builder[::-1])
    print(line)
