从.txt文件

Question

我有一个包含一些值的.txt文件。我需要使用python一次获取两个值并对其执行一些操作，然后获取接下来的两个值。

我想写一个python脚本，我可以一次获取两个值。我是python的新手。

谢谢！

Answer 1

# Read the file first and split lines in a list
with open('temp.txt', 'r') as f:
    lines = f.read().splitlines()

# Loop through lines, two at a time
for i in range(0, len(lines), 2):   # Notice the last argument '2', it makes the loop step 2 at a time
    val1 = lines[i]
    val2 = lines[i+1]
    # Perform calculation on val1 and val2

希望这有帮助。
