Answer:
Hi there! The question can easily be implemented by iterating through the array list an using the "startswith()" function of the String class. Please find explanation below.
Explanation:
We can write the code as below into a file called starts_with.py and run it from the command line. Sample input is also provided with results.
starts_with.py
import sys;
def starts_with(prefix, wordlist):
for e in wordlist:
if e.lower().startswith(prefix.lower()):
starts_with_array.append(e);
starts_with_array = [];
prefix = input("Enter prefix: ");
wordlist = input("Enter word list: ");
wordlist = wordlist.split(',');
starts_with(prefix, wordlist);
print(starts_with_array);
Usage with Result
> starts_with.py
> Enter prefix: Fun
> Enter word list: Funtastic,Fun,Test,No
> ['Funtastic', 'Fun']
Answer:
The program written in Python is as follows:
file_handler = open("numbers.dat","r")
nums = 0
for line in file_handler:
try:
nums+=int(line)
except ValueError:
continue
file_handler.close()
print("Sum: "+str(nums))
Explanation:
The file handler is used to enable the program reads content of the file numbers.dat
file_handler = open("numbers.dat","r")
This initializes the sum of numbers to 0
nums = 0
This iterates through the line of the file
for line in file_handler:
The try exception is used to prevent program crash if data other than integer is read
try:
This adds numbers on each line
nums+=int(line)
This exception is returned for data other than integers
except ValueError:
continue
This closes the file handler
file_handler.close()
This prints the calculated sum
print("Sum: "+str(nums))

True, you can because in Scratch, you actually can use an if statement block and use an if touching another sprite.
