使用 python 打印范围之间的奇数或偶数列表。 输出应与字符串在一行中

Question

这是我的代码：

start=int(input('enter the starting range:'))
end=int(input('enter the ending range:'))
for d in range(start,end):
    if d%2!=0:
        print('The odd numbers between',start,'&',end,'is:',d)

当前输出为：

enter the starting range:20
enter the ending range:30
The odd numbers between 20 & 30 is: 21
The odd numbers between 20 & 30 is: 23
The odd numbers between 20 & 30 is: 25
The odd numbers between 20 & 30 is: 27
The odd numbers between 20 & 30 is: 29

想要的输出是：

'The odd numbers between 20 & 30 is: 21,23,25,27,29'

我需要做哪些改变？

Answer 1

使用列表理解，你可以让它更短

start=int(input('enter the starting range:'))
end=int(input('enter the ending range:'))

# New lines
numbers = ", ".join([str(i) for i in range(start, end) if i % 2 != 0])
print(f"The odds numbers between {start} and {end} are:", numbers)

Answer 2

在循环之前打印消息，然后在循环期间打印数字：

start = int(input('enter the starting range:'))
end = int(input('enter the ending range:'))
# use end='' to avoid printing a newline at the end
print(f'The odd numbers between {start} & {end} is: ', end='')
should_print_comma = False
for d in range(start,end):
    if d%2!=0:
        # only start printing commas after the first element
        if should_print_comma:
            print(',', end='')
        print(d, end='')
        should_print_comma = True

Answer 3

start=int(input('enter the starting range:'))
end=int(input('enter the ending range:'))
s = ""
for d in range(start,end):
    if d%2!=0:
        s += str(d) + ", ";
print('The odd numbers between',start,'&',end,'is:',s)

你可能应该把它放在一个函数中，但这只是一个偏好。

简单且非常简洁的解决方案：（添加我的评论，以便您了解我所做的）

start = int(input('enter the starting range: '))
end = int(input('enter the ending range: '))

#create an empty list
numbers = []
for d in range(start,end):
    if d % 2 != 0:
      #if number is odd, add it to the list
      numbers.append(d)

#we use end=" " to make sure there is no new line after first print
print('The odd numbers between',start,'&',end,'are:',end=" ")

#* symbol is used to print the list elements in a single line with space. To print all elements in new lines or separated by space use sep=”\n” or sep=”, ” respectively
print(*numbers,sep = ",")
