python delete double white space between columns from txt file and save result in new file

I have txt file 1 has the following contents:

AW_003015.1     156   VPSELGGVGLKNTQYARLVEI
AS_010029.1     215       LASGETVAAFKLTEPSSGSDA
CE_010039.1     433   SEAAWKVTDEKIQIMGGMGFM
RN_000019.1     477      ILRLFVALQGKMDKGKELSGL
DP_020039.1     603      HPTAQHEKMLKDTWCIEAAAR

I want to make single line space between columns and save that in new txt file as following:

AW_003015.1 156 VPSELGGVGLKNTQYARLVEI
AS_010029.1 215 LASGETVAAFKLTEPSSGSDA
CE_010039.1 433 SEAAWKVTDEKIQIMGGMGFM
RN_000019.1 477 ILRLFVALQGKMDKGKELSGL
DP_020039.1 603 HPTAQHEKMLKDTWCIEAAAR

This is my code I did not be able to do that:

outfile = open(“file2.txt”, “w”) # Clears existing file, open for writing

with open(“file1.txt”) as infile:

for line in infile:

line = line.strip()

#print(line)

if line:

line = line.strip()

while ‘ ‘ in line:

line = line.replace(‘ ‘, ”)

print(line)

outfile.write(line)
