或者分三种(作者：SupercraftD)

import math
import sys

# Auto-generated code below aims at helping you parse
# the standard input according to the problem statement.

# length = int(input())
# c = input()
length = 4
c = "R"

rows = []

# 这里row构建出来['   R', '  R', ' R']
for i in range(1, length):
    rows.append(" " * (length - i) + c)
# 然后解包为参数，设置参数之间以\n分隔，构成
#    R
#   R
#  R
print(*rows, sep="\n")
# 单独输出一个
# R
print(c)
# 倒序输出
#  R
#   R
#    R
print(*rows[::-1], sep="\n")

判断

不推荐第一种写法

import math
import sys

# Auto-generated code below aims at helping you parse
# the standard input according to the problem statement.

n = int(input())

for i in range(1, n + 1):
    if i % 3 == 0 and i % 5 == 0 and i % 4 == 0:
        print("FizzBuzzBar")

    if i % 3 == 0 and i % 4 == 0 and i % 5 != 0:
        print("FizzBar")
    if i % 5 == 0 and i % 4 == 0 and i % 3 != 0:
        print("BuzzBar")
    if i % 5 == 0 and i % 3 == 0 and i % 4 != 0:
        print("FizzBuzz")

    if i % 3 == 0 and i % 4 != 0 and i % 5 != 0:
        print("Fizz")
    if i % 5 == 0 and i % 3 != 0 and i % 4 != 0:
        print("Buzz")
    if i % 4 == 0 and i % 3 != 0 and i % 5 != 0:
        print("Bar")

    if i % 3 != 0 and i % 4 != 0 and i % 5 != 0:
        print(i)

没必要这样写，观察结果

n = int(input())

for i in range(1, n + 1):
    output = ""
    if i % 3 == 0:
        output += "Fizz"
    if i % 5 == 0:
        output += "Buzz"
    if i % 4 == 0:
        output += "Bar"
    if output == "":
        output = str(i)
    
    print(output)
