Question

我有一个数据集，我将从文本文件中读取：

0.0000000e+000 -1.4275799e-003  
2.0000000e-002 -1.1012760e-002  
4.0000000e-002 -1.0298970e-002  
6.0000000e-002 -8.9733599e-003  
8.0000000e-002 -9.6871497e-003  
1.0000000e-001 -1.2236400e-002  
1.2000000e-001 -1.4479739e-002  
1.4000000e-001 -1.3052160e-002  
1.6000000e-001 -1.1216700e-002  
1.8000000e-001 -8.6674497e-003  
2.0000000e-001 -8.6674497e-003  
2.2000000e-001 -1.3358070e-002  
2.4000000e-001 -1.7946720e-002  
2.6000000e-001 -1.9782179e-002

我希望在将文本文件读取为以下格式后进行转换：

(0.0000000e+000, -1.4275799e-003), (2.0000000e-002, -1.1012760e-002), (4.0000000e-002, -1.0298970e-002), ..., (2.6000000e-001, -1.9782179e-002)

应该排成一行。

有人可以帮我这个吗？我的代码如下：

with open('1.txt') as f:    
    for line in f:    
        n0 = map(float, line.split())    
        n1 = tuple(n0)    
        n2 = zip(n1)    
        print n0

我没有收到任何错误，但问题是zip命令没有在行中提供所需的格式。

Answer 1

with open("1.txt" , "rb") as txtfile:
        outputstr = ""
        ioreader = txtfile.read()
        for line in ioreader.split("\n"):
            outputstr += str(tuple(line.split("\t")))
            outputstr += ","
        print outputstr

Answer 2

下面的代码应该完成工作：

def load_data(fn):
    with open(fn) as f:    
        lines = f.readlines()
    return [tuple(map(float, x)) for x in [row.split() for row in lines]]

def display_data(lst):
    return lst.__repr__()[1:-1]

ppp = load_data('1.txt')

print display_data(ppp)
#(0.0, -0.0014275799), (0.02, -0.01101276), (0.04, -0.01029897), (0.06, -0.0089733599), (0.08, -0.0096871497), (0.1, -0.0122364), (0.12, -0.014479739), (0.14, -0.01305216), (0.16, -0.0112167), (0.18, -0.0086674497), (0.2, -0.0086674497), (0.22, -0.01335807), (0.24, -0.01794672), (0.26, -0.019782179)

print ppp
#[(0.0, -0.0014275799),
# (0.02, -0.01101276),
# (0.04, -0.01029897),
# (0.06, -0.0089733599),
# (0.08, -0.0096871497),
# (0.1, -0.0122364),
# (0.12, -0.014479739),
# (0.14, -0.01305216),
# (0.16, -0.0112167),
# (0.18, -0.0086674497),
# (0.2, -0.0086674497),
# (0.22, -0.01335807),
# (0.24, -0.01794672),
# (0.26, -0.019782179)]
