import osdef create_python_script(filename): comments = "# Start of a new Python Program" #filesize = 0 with open(filename, 'w') as new_file: new_file.write(comments) cwd=os.getcwd() fpath = os.path.abspath(filename) filesize=os.path.getsize(fpath) return(filesize)print(create_python_script('newprogram.py'))我得到的結(jié)果為零，但它應(yīng)該得到“31”

在嘗試獲取文件大小之前，您沒有關(guān)閉文件，就像在塊內(nèi)所做的那樣。把它帶到外面：with
import os
def create_python_script(filename):
comments = "# Start of a new Python Program"
#filesize = 0
with open(filename, 'w') as new_file:
new_file.write(comments)
cwd=os.getcwd()
fpath = os.path.abspath(filename)
print(fpath)
filesize=os.path.getsize(fpath)
return(filesize)
print(create_python_script('newprogram.py'))
# 31

import os
def create_python_script(filename):
comments = "# Start of a new Python program"
with open(filename, 'w') as file:
file.write(comments)
file.close()
filepath = os.path.abspath(filename)
filesize = os.path.getsize(filepath)
return(filesize)
print(create_python_script("program.py"))
#this will give you correct result

這個也工作得很好！
def create_python_script(filename):
import os
comments = "# Start of a new Python program"
with open(filename,'w')as file:
file.write(comments)
filesize = os.path.getsize(filename)
return(filesize)
print(create_python_script("program.py"))

首先打開具有寫入權(quán)限的文件，以在文件中添加文本。然后以讀取權(quán)限打開文件以獲取文件的大小。
import os
def create_python_script(filename):
comments = "# Start of a new Python program"
with open(filename, 'w') as pd:
pd.write(comments)
with open(filename, "r"):
filesize = os.path.getsize(filename)
print(filesize)
return filesize
print(create_python_script("program.py"))
