Python -更优雅的解决方案？

Question

这产生了所需的输出，但我看到它不是一个优雅的解决方案(重复三个相似的循环)。这怎么能被浓缩？它能浓缩到多大程度才能使它尽可能的简短/优雅呢？提前感谢

for planet in range(1): #this produces the rows (is this line needed?)


    for column in range(1,6): #this produces the numbers
        print(column, end="***") 
    print()
    for column in range(6,11):
        print(column,end="***")
    print()
    for column in range(11,15):
        print(column,end="***")
    print()

Answer 1

你可以这样做：

for item in range(1,16):
    if item % 5 == 0:
        print(item, "***", sep='')
        continue

    print(item, "***", sep='',end='')

它还返回相同的结果。

1***2***3***4***5***
6***7***8***9***10***
11***12***13***14***15***

您还可以替换函数中的变量，使其更易读，如果需要修改行数和列数。

numColumns = 5
numValues = 15

for item in range(1,numValues+1):
    if item % numColumns == 0:  # If it is the last column in the row
        print(item, "***", sep='')  # Print the final column and a newline character (the default end character)
        continue  # Last column in row, skip the rest of the for loop and return to beginning

    print(item, "***", sep='',end='')  # Print the first few columns without a newline end character


# in the print() function:
#  'sep' is the separator between items in the print() function
#  'end' is the special character at the end of the print statement, which is by default the newline '\n'
