获取i和j条件匹配的行

Question

打印每个输出一次： f1=['part3_pl',      'part2_pl',      'part3_pl_to_p',      'part2_pl_to_p',      'part3_pl_to_p_lack',      'part2_pl_to_p_lack']for i in f1:    for j in f1:        if i.endswith('pl') and j.endswith('pl_to_p'):            print(i,j,i+'_output')返回值：part3_pl part3_pl_to_p part3_pl_outputpart3_pl part2_pl_to_p part3_pl_outputpart2_pl part3_pl_to_p part2_pl_outputpart2_pl part2_pl_to_p part2_pl_output我想每行打印一次。正确的输出：part3_pl part3_pl_to_p part3_pl_outputpart2_pl part2_pl_to_p part2_pl_output

Answer 1

请再次检查输出。根据您的代码，输出应为：

for i in f1:

 for j in f1:

    if i.endswith('pl') and j.endswith('pl_to_p'):

        print(i,j,i+'_output') 

输出 ：

part3_pl part3_pl_to_p part3_pl_output

part3_pl part2_pl_to_p part3_pl_output

part2_pl part3_pl_to_p part2_pl_output

part2_pl part2_pl_to_p part2_pl_output

所需的输出可以通过以下代码实现：

for i in f1:

 for j in f1:

  if i.endswith('pl') and j==i+ '_to_p':

    print(i,j,i+'_output')
