Python代码只打印以A开头的字母[副本]

只需使用 startswith

w = ["Algorithm", "Logic", "Filter", "Software", "Network", "Parameters", "Analyze", "Algorithm", "Functionality", "Viruses"]

for word in w:
    if word.startswith('A'):
        print(word)

>>> Algorithm
>>> Analyze
>>> Algorithm

编辑:因为你不能使用 开始使用

for word in w:
    if word[0] == 'A':
        print(word)

如果要将其存储在列表中,也可以使用列表理解:

result = [word for word in w if word[0] == "A"]

或者,只是简单的循环(如果你只想把单词打印出来):

for word in w:
    if word[0] == "A":
        print(word)
