py args 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: pass argument to a py file
import sys
def hello(a,b):
print "hello and that's your sum:", a + b
if __name__ == "__main__":
a = int(sys.argv[1])
b = int(sys.argv[2])
hello(a, b)
# If you type : py main.py 1 5
# It should give you "hello and that's your sum:6"
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 *args
# concatenate_keys.py
def concatenate(**kwargs):
result = ""
# Iterating over the keys of the Python kwargs dictionary
for arg in kwargs:
result += arg
return result
print(concatenate(a="Real", b="Python", c="Is", d="Great", e="!"))
