【Python】读写多行文件的几种写法
# code 0: just for small file
with open(filepath, 'r') as f:
for line in f.readlines():
[somecode here to process each line]
# code 1.1
with open(filepath, 'r') as f:
while True:
line = f.readline()
if not line:
break
[somecode here to process each line]
# code 1.2
with open(filepath, 'r') as f:
line = f.readline()
while line:
[some code here to process each line]
line = f.readline()
# code 2.1
with open(filepath, 'r') as f:
for line in f:
[some code here to process each line]
# code 2.2: skip the first line
with open(filepath, 'r') as f:
next(f)
for line in f:
[some code here to process each line]
# code 2.3: skip but save the first line (e.g. header line)
with open(filepath, 'r') as f:
header_line = f.readline()
for line in f:
[some code here to process each line]
