阅读.csv文件。

Question

我有一个.csv文件，我需要循环，然后在循环内，我想检查每次迭代的下一行的值。我似乎无法让它正常工作，因为它跳过了我在下一次迭代中向前看的线。

import csv
file_object = open('file.csv', 'r')
reader = csv.reader(file_object, delimiter = ';')

for line in reader:
    next_line = reader.next()
    # It now reads the next line and doesn't iterate over it again in the next
    # iteration. However, i want it to still iterate over it in the next iteration.

非常感谢！

您可以“手动：”

跟踪当前和下一行

line = reader.next()
for next_line in reader:
    # Do your processing
    line = next_line
# Now do whatever needs to be done with the very last line
