fileHandler = open ("data.txt", "r") # Get list of all lines in file listOfLines = fileHandler.readlines() # Close file fileHandler.close() 1. 2. 3. 4. 5. 6. 它将返回文件中的行列表。我们可以遍历该列表,并剥离()新行字符,然后打印该行,即
To iterate over lines of two different files, we can open both files simultaneously and read lines of each file inside the same for loop. Here is an example: filename1="file1.txt"filename2="file2.txt"withopen(filename1,"r")asfile1,open(filename2,"r")asfile2:forline1,line2inzip...
file2 = open("output.txt","w")for line in open("test.txt"): #这里可以进行逻辑处理 file2.write('"'+line[:s]+'"'+",")第三种方法：文件上下文管理器 with open('somefile.txt', 'r') as f: data = f.read()# Iterate over the lines of the filewith open('somefile.txt'...

f = open(sys.argv[1],"r") lines = f.readlines() f.close() The crypt module will allow us to compute crypted passwords inside Python. We open the filename that was passed on the command line and specify that it should be opened as read-only. We read the file lines into a list...

Duck typing often works well with anEAFPprogramming style. For example, if a function accepts a readable file-like object, it may assume the given argument is aniterableof lines and loop over it. If a non-iterable was given, the program would raise an exception, either explicitly or implici...
With pathlib, you can conveniently use the .iterdir() method, which iterates over all the files in the given directory. In the following example, you combine .iterdir() with the collections.Counter class to count how many files of each file type are in the current directory: Python >>...
