I want to input a command-line variable and then multiply it, but when I print the variable it repeats by the number I want to multiply it by.

eg:

```
#!/usr/bin/env python3
import sys
st_run_time_1 = sys.argv[1]*60

print ("Station 1 : %s" % st_run_time_1)

```

When I run the script I get the following:
 python3 test.py 2

```
Station 1 : 222222222222222222222222222222222222222222222222222222222222

```
