如何将制表符扩展到空格并排列列表格式？

Question

我的问题是如何将制表符扩展到空格并排列列表格式？

数据以单个字符串显示

'Patient_ID\tAge\tGender\tTumor_Size\tNearby_Cancer_Lymphnodes\tCancer_Spread\tHistological_Type\tLymph_Nodes\tTreatment\ntcga.5l.aat0\t42\tfemale\tt2\tn0\tm0\th_t_1\t0\tplan_1\ntcga.aq.a54o\t51\tmale\tt2\tn0\tm0\th_t_2\t0\tplan_2\ntcga.aq.a7u7\t55\tfemale\tt2\tn2a\tm0\th_t_1\t4\tplan_4\n'`

我希望输出与以下相同。

Patient_ID     Age    Gender    Tumor_Size    Nearby_Cancer_Lymphnodes    
tcga.5l.aat0   42     female    t2            n0

import pandas as pd

string = 'Patient_ID\tAge\tGender\tTumor_Size\tNearby_Cancer_Lymphnodes\tCancer_Spread\tHistological_Type\tLymph_Nodes\tTreatment\ntcga.5l.aat0\t42\tfemale\tt2\tn0\tm0\th_t_1\t0\tplan_1\ntcga.aq.a54o\t51\tmale\tt2\tn0\tm0\th_t_2\t0\tplan_2\ntcga.aq.a7u7\t55\tfemale\tt2\tn2a\tm0\th_t_1\t4\tplan_4\n'

lines = string.split('\n')[0:-1] # Split string by '\n', ignoring the last one
data = [line.split('\t') for line in lines] # Split strings by '\t'
df = pd.DataFrame(data) # Create a pandas data frame from the data
print(df)

              0    1       2           3                         4              5                  6            7          8

如果你想处理数据我会推荐pandas包，并将字符串读取为像这样的文件StringIO

from io import StringIO
import pandas as pd

s = """Patient_ID\tAge\tGender\tTumor_Size\tNearby_Cancer_Lymphnodes\tCancer_Spread\tHistological_Type\tLymph_Nodes\tTreatment\ntcga.5l.aat0\t42\tfemale\tt2\tn0\tm0\th_t_1\t0\tplan_1\ntcga.aq.a54o\t51\tmale\tt2\tn0\tm0\th_t_2\t0\tplan_2\ntcga.aq.a7u7\t55\tfemale\tt2\tn2a\tm0\th_t_1\t4\tplan_4\n"""
df = pd.read_csv(StringIO(s), sep="\t")
