在下面的列表中，我想將“Sun”替換為 0，將“Rain”替換為 1。我該怎么做？precipitation = ["Sun", "Rain", "Rain", "Sun", "Sun", "Sun", "Sun", "Sun", "Sun", "Sun", "Rain", "Rain", "Rain", "Rain"]for i in precipitation: if precipitation[i] == "Sun": precipitation[i] = 0 else: precipitation[i] = 1

您可以使用列表理解來做到這一點：
precipitation = [0 if x == 'Sun' else 1 for x in precipitation]

使用布爾值用數(shù)字表示為 0 和 1 的事實來詳細闡述 @Gabip 的答案：
[int(x=='Sun') for x in precipitation]

添加到已經(jīng)存在的答案中，使用map()
list(map(lambda x: 0 if x=='Sun' else 1,a))
您可以嘗試這樣做以避免循環(huán)和列表理解

嘗試這個...
precipitation = ["Sun", "Rain", "Rain", "Sun", "Sun", "Sun", "Sun", "Sun", "Sun", "Sun", "Rain", "Rain", "Rain", "Rain"]
for i in range(len(precipitation)):
if precipitation[i] == "Sun":
precipitation[i] = 0
else:
precipitation[i] = 1
print(precipitation)
