從python中的某一行開始讀取

Question

是否可以從某一行開始讀取？在我下面舉的例子，我想讀的，只有從Line04使用起

with open (fileList[0], 'rt') as filehandle: 
    for line in filehandle: 
     print line 

# Output: 
# This is a testing file 
# 
# v 1.05 
# v -2.15 

Answer 1

這應該工作：

with open('your_file', 'rt') as filehandle: 
    lines = filehandle.readlines()[4:] 

for line in lines: 
    print line 
    #do something 

Answer 2

lineno = 0 
for line in filehandle: 
    lineno = lineno + 1 
    if(lineno > 4): 
     print line 

Answer 3

您可以直接跳過前四線，採用enumerate算來：

with open(fileList[0], 'rt') as filehandle: 
    for line_num, line in enumerate(filehandle): 
     if line_num < 4: 
      continue 

     print line 
     # and do anything else
