Question

import csv
import os
import glob

# Your folder location where the input files are saved.
name_of_folder = '...'  
output_filename = 'output.txt'
input_files = glob.glob(os.path.join(name_of_folder, '*.txt'))

with open(os.path.join(name_of_folder, output_filename), 'w') as file_out:
    headers_read = False
    for input_file in input_files:
        if input_file == os.path.join(name_of_folder, output_filename):
            # If the output file is in the list of input files, ignore it.
            continue
        with open(input_file, 'r') as fin:
            reader = csv.reader(fin)
            if not headers_read:
                # Read column headers just once
                headers = reader.next()[0].split()
                headers = headers[2:4] + [headers[9]]
                file_out.write("\t".join(headers + ['\n']))  # Zero based indexing.
                headers_read = True
            else:
                _ = reader.next()  # Ignore header row.
            for line in reader:
                if line:  # Ignore blank lines.
                    line_out = line[0].split()
                    file_out.write("\t".join(line_out[2:4] + [line_out[9]] + ['\n']))

>>> !cat output.txt
gene    locus   log2(fold_change)   
ZZ  1:1 0   
ZZ  1:1 0

在本规范中，我有两种不同的输出，但写作方式相同吗？

x1的唯一区别是function test（）;而x2是test（）;只有没有关键字“功能”你可以向我解释为什么我有两个不同的输出？

Answer 1

这声明/定义函数test：

function test(){
    echo"x1 is: $x";
}

这会调用函数test：

test();

然后在这个例子中，echo发生在任何函数之外。

Answer 2

您正在第一个中定义一个函数。

您正在调用第二个函数，然后调用echo "x2 is: $x"。

function test（）有什么区别;和test（）;用PHP？
