The output of `int("1.4")` will be a `ValueError` because the string "1.4" cannot be converted to an integer directly since it contains a decimal point and is not a whole number. To convert a string containing a floating-point number to an integer, you would need to first convert it to a float and then round or truncate it to an integer.

a)The (>) operator can be used to redirect the output of a command (what would normally be printed on the screen) into a file. Redirect the output of the ls and ps commands into files.
To redirect the output of the `ls` and `ps` commands into files, we can use the `>` operator followed by the file name to which we want to write the output. Here are the commands:
1. Redirecting the output of `ls` command to a file named `list.txt`:
```
ls > list.txt
```
This command will write the output of `ls` command (i.e., the list of files and directories in the current directory) to a file named `list.txt`.
2. Redirecting the output of `ps` command to a file named `processes.txt`:
```
ps > processes.txt
```
This command will write the output of `ps` command (i.e., the list of running processes) to a file named `processes.txt`.
Note that if the file already exists, the output will overwrite the existing contents of the file. If you want to append the output to the existing content of the file, you can use the `>>` operator instead of `>`.
return the number of even ints in the given array.
Sure! Here's a Python function that takes an array of integers and returns the count of even integers:
```python
def count_evens(nums):
count = 0
for num in nums:
if num % 2 == 0:
count += 1
return count
```
You can call this function with an array of integers like this:
```python
nums = [1, 2, 3, 4, 5, 6]
count = count_evens(nums)
print(count) # Output: 3
```
This will output the count of even integers in the `nums` array, which is 3 in this case. Let me know if you have any other questions!
