我很難將2個函數嵌套到更大的函數中,因此函數將打開並讀取文件並打印結果。沒有錯誤,但結果顯示爲None
。請讓我知道我可以如何改進代碼。先謝謝你!嵌套函數-python
import glob
#Read a result file and return a list
def read_results(filename):
text_file=open(filename,"r")
lines=text_file.readlines()
return lines
text_file.close()
#Give a list of results files in your directory
def get_filename():
filelist=glob.glob("./Data/*.*")
return filelist
#Call above functions to get file names and read each file
def read_lines(filename):
def get_filename()
def read_results():
print lines
#main
function=read_results("./Data/GSM21203-GSM21215.csv")
print"\nHere's the lines of the text file:", function
#In order to use the strip method, it must be a str. Currently I am not using a string. Figure out how to do it
print"\n"
list_of_filenames=get_filename()
print"Here are the list of filenames:",list_of_filenames
read_each_file=read_lines("*.*")
print "Here are the contents of each file",read_each_file
謝謝你的迴應,我是一名初學者學習Python,並且我仍然試圖理解函數。你有什麼建議嗎? – user1521735 2012-07-12 20:10:53
是的,我建議你閱讀我在答案中鏈接的Python教程。 – BrenBarn 2012-07-13 03:35:42
