如果df1的值在df2的范围内，则在df1中添加新列

Question

比较两个数据帧。如果df1的值与df2列的值重叠，则应添加一个新列，其值为'Yes'或'No'。

条件：

if df1['chr'] == df2['chr']
   df1['Status'] = df1['position'].between(df2['start'],df2['end']

df1<tab separated>
name    chr position
res1    c1  98
res2    c4  143
res3    c1  108

df2<tab separated>
chr start   end
c1  78  97
c2  108 143
c1  143 108

输出：

res1    c1  98  no
res2    c4  143 no
res3    c1  108 yes 

def overlap_region(H3K27ac_file,snp_list):
    df1 = pd.read_csv(H3K27ac_file, sep="\t",header=None,header=0)
    df2 = pd.read_csv(snp_list, sep="\t",header=0)

    df1['position'].between(df2['start'],df2['end']

    print(df1)
x = overlap_region(x,y)
