Python double for函数

Question

我构建这个Python代码的目的是将每个名字与姓氏相匹配：

first_names = ['Jane','Sam','Deborah']
last_names = ['Simmons','Kaybone','Stone']

for f_name in first_names:
    for l_name in last_names:
        print(f_name.title() + " " + l_name.title())

但是很明显，我的代码会打印出所有的名字和姓，而不仅仅是（1,1）、（2,2）、（3,3）。如何调整此代码？谢谢！你知道吗

Answer 1

您正在寻找^{}：

first_names = ['Jane','Sam','Deborah']
last_names = ['Simmons','Kaybone','Stone']
for f, l in zip(first_names, last_names):
    print(f.title(),l.title())

输出：

Jane Simmons
Sam Kaybone
Deborah Stone

一行：

print(*(f'{f.title()} {l.title()}' for f, l in zip(first_names, last_names)),sep='\n')

编辑： 正如Peter Wood正确指出的：

print(*(f'{f} {l}'.title() for f, l in zip(first_names, last_names)),sep='\n')

Answer 2

你想要的是zip()：

first_names = ['Jane','Sam','Deborah']
last_names = ['Simmons','Kaybone','Stone']

for f_name, l_name in zip(first_names, last_names):
  print(f_name + " " + l_name)
