Given a list of numbers, write a Python program to count positive and negative numbers in a List.

**Example:**

Input:list1 = [2, -7, 5, -64, -14]Output:pos = 2, neg = 3Input:list2 = [-12, 14, 95, 3]Output:pos = 3, neg = 1

**Example #1:** Count positive and negative numbers from given list using for loop

Iterate each element in the list using for loop and check if num >= 0, the condition to check positive numbers. If the condition satisfies, then increase pos_count else increase neg_count.

`# Python program to count positive and negative numbers in a List` ` ` `# list of numbers` `list1 ` `=` `[` `10` `, ` `-` `21` `, ` `4` `, ` `-` `45` `, ` `66` `, ` `-` `93` `, ` `1` `]` ` ` `pos_count, neg_count ` `=` `0` `, ` `0` ` ` `# iterating each number in list` `for` `num ` `in` `list1:` ` ` ` ` `# checking condition` ` ` `if` `num >` `=` `0` `:` ` ` `pos_count ` `+` `=` `1` ` ` ` ` `else` `:` ` ` `neg_count ` `+` `=` `1` ` ` `print` `(` `"Positive numbers in the list: "` `, pos_count)` `print` `(` `"Negative numbers in the list: "` `, neg_count)` |

**Output:**

Positive numbers in the list: 4 Negative numbers in the list: 3

**Example #2:** Using while loop

`# Python program to count positive and negative numbers in a List` ` ` `# list of numbers` `list1 ` `=` `[` `-` `10` `, ` `-` `21` `, ` `-` `4` `, ` `-` `45` `, ` `-` `66` `, ` `93` `, ` `11` `]` ` ` `pos_count, neg_count ` `=` `0` `, ` `0` `num ` `=` `0` ` ` `# using while loop ` `while` `(num < ` `len` `(list1)):` ` ` ` ` `# checking condition` ` ` `if` `list1[num] >` `=` `0` `:` ` ` `pos_count ` `+` `=` `1` ` ` `else` `:` ` ` `neg_count ` `+` `=` `1` ` ` ` ` `# increment num ` ` ` `num ` `+` `=` `1` ` ` `print` `(` `"Positive numbers in the list: "` `, pos_count)` `print` `(` `"Negative numbers in the list: "` `, neg_count)` |

**Output:**

Positive numbers in the list: 2 Negative numbers in the list: 5

**Example #3 :** Using Python Lambda Expressions

`# Python program to count positive` `# and negative numbers in a List` ` ` `# list of numbers` `list1 ` `=` `[` `10` `, ` `-` `21` `, ` `-` `4` `, ` `45` `, ` `66` `, ` `93` `, ` `-` `11` `]` ` ` `neg_count ` `=` `len` `(` `list` `(` `filter` `(` `lambda` `x: (x < ` `0` `), list1)))` ` ` `# we can also do len(list1) - neg_count` `pos_count ` `=` `len` `(` `list` `(` `filter` `(` `lambda` `x: (x >` `=` `0` `), list1)))` ` ` `print` `(` `"Positive numbers in the list: "` `, pos_count)` `print` `(` `"Negative numbers in the list: "` `, neg_count)` |

**Output:**

Positive numbers in the list: 4 Negative numbers in the list: 3

**Example #4 : **Using List Comprehension

`# Python program to count positive` `# and negative numbers in a List` ` ` `# list of numbers` `list1 ` `=` `[` `-` `10` `, ` `-` `21` `, ` `-` `4` `, ` `-` `45` `, ` `-` `66` `, ` `-` `93` `, ` `11` `]` ` ` `only_pos ` `=` `[num ` `for` `num ` `in` `list1 ` `if` `num >` `=` `1` `]` `pos_count ` `=` `len` `(only_pos)` ` ` `print` `(` `"Positive numbers in the list: "` `, pos_count)` `print` `(` `"Negative numbers in the list: "` `, ` `len` `(list1) ` `-` `pos_count)` |

**Output:**

Positive numbers in the list: 1 Negative numbers in the list: 6
