在下面的程序中
我想从下游函数中的一个函数访问/管道数据。
使用 python 代码如下:
def main():
data1, data2, data3 = read_file()
do_calc(data1, data2, data3)
def read_file():
data1 = ""
data2 = ""
data3 = ""
file1 = open('file1.txt', 'r+').read()
for line in file1
do something....
data1 += calculated_values
file2 = open('file2.txt', 'r+').read()
for line in file1
do something...
data2 += calculated_values
file1 = open('file1.txt', 'r+').read()
for line in file1
do something...
data3 += calculated_values
return data1, data2, data3
def do_calc(data1, data2, data3):
d1_frame = pd.read_table(data1, sep='\t')
d2_frame = pd.read_table(data2, sep='\t')
d3_frame = pd.read_table(data3, sep='\t')
all_data = [d1_frame, d2_frame, d3_frame]
chủ yếu()
给定的代码有什么问题?看起来 panda 无法正确读取输入文件,而是将数据 1、2 和 3 的值打印到屏幕上。
read_hdf 似乎读取文件但不正确。有没有办法将函数返回的数据直接读入 pandas(无需写入/读入文件)。

如有任何解释,我将不胜感激。
