如何讀取以python中的算術字符開頭的行3

Question

我正在使用readline讀取文件，但其中一些行以算術字符開頭，readline跳過此行， 有任何建議？

with open(path) as program_file: 
for line in program_file: 
    line = program_file.readline() 
    print(line) 

一些線路是這樣的：

2 4 5 
+ 3 #skip this line 
_ 5 9 

Answer 1

這不是開始與字符的問題的線，它是在for line in x和x.readline語句都從文件中讀取一條線，讓你」可能會打印出備用行。刪除readline！

with open(path) as program_file: 
    for line in program_file: 
     print(line)
