  File "<input>", line 1, in <module>

import platform
import subprocess 
import sys

try:
    import pandas
except ModuleNotFoundError:
    if platform.system() == 'Windows':
        subprocess.call([sys.exec_prefix + '/python', "-m", 'pip', 'install', 'pandas'])
    else:
        subprocess.call(['python3', '-m', 'pip', 'install', 'pandas']) 
    import pandas
