get input arguments python code example
Example 1: python get command line arguments
import sys
print("This is the name of the script:", sys.argv[0])
print("Number of arguments:", len(sys.argv))
print("The arguments are:" , str(sys.argv))
#Example output
#This is the name of the script: sysargv.py
#Number of arguments in: 3
#The arguments are: ['sysargv.py', 'arg1', 'arg2']
Example 2: python arguments
import sys
print ("the script has the name %s" % (sys.argv[0])
Example 3: program arguments python
#!/usr/bin/python
import sys
for args in sys.argv:
print(args)
"""
If you were to call the program with subsequent arguments, the output
will be of the following
Call:
python3 sys.py homie no
Output:
sys.py
homie
no
"""
Example 4: python main args
#!/usr/bin/python
import sys, getopt
def main(argv):
inputfile = ''
outputfile = ''
try:
opts, args = getopt.getopt(argv,"hi:o:",["ifile=","ofile="])
except getopt.GetoptError:
print 'test.py -i <inputfile> -o <outputfile>'
sys.exit(2)
for opt, arg in opts:
if opt == '-h':
print 'test.py -i <inputfile> -o <outputfile>'
sys.exit()
elif opt in ("-i", "--ifile"):
inputfile = arg
elif opt in ("-o", "--ofile"):
outputfile = arg
print 'Input file is "', inputfile
print 'Output file is "', outputfile
if __name__ == "__main__":
main(sys.argv[1:])
