我正在尝试编写一个Python程序,该程序将以块的形式打印出99瓶啤酒的歌词,我已经开始工作了。但是,我需要在最后一行说“ 1瓶啤酒”,而不是“ 1瓶啤酒”。
我将代码包装在if语句中,但是if语句似乎被忽略了。我在做什么错了?
verse = '''
{some} bottles of beer on the wall
{some} bottles of beer
Take one down, pass it around
{less} bottles of beer on the wall
'''
verse2 = '''
{some} bottles of beer on the wall
{some} bottles of beer
Take one down, pass it around
1 bottle of beer on the wall
'''
for bottles in range(99 , 1, -1):
if bottles >= 2:
print(verse.format(some = bottles, less = bottles - 1))
else:
print(verse2.format(some = bottles))

尝试一下:
PHP
$History_Assoc = mysqli_fetch_array($HistoryQuery);
echo '<ul class="repoFolder" data-value=" {lat: '.(float)$History_Assoc['latitude'].', lng: '.(float)$History_Assoc['longitude'] .'} ">';
echo '<br>';
JAVASCRIPT
var folders = document.getElementsByClassName("repoFolder");
for (let i = 0; i < folders.length; i++) {
folders[i].onclick = function() {rootFolder.call(this)}; // note that I am passing in the context to rootFolder.
}
function rootFolder() {
var variable = this.getAttribute('data-value');
alert(variable);
var markersHistory = new google.maps.Marker({
position: variable,
map: map,
icon: iconBlue2,
});
}
结果应为:
print(list(range(99 , 1, -1)))
数字1从未出现。
要解决此问题,只需将[99, 98, 97, ..., 5, 4, 3, 2]
更改为range(99, 1, -1)
。

范围不包含端点,因此范围的最后一个元素不是1而是2。
您应该将if语句改为if bottles > 2:
,输出将是正确的。
