# Python Exercises: Capitalize the first letter and lowercases the rest

## Python String: Exercise-104 with Solution

Write a Python program that capitalizes the first letter and lowercases the remaining letters of a given string.

Sample Data:
(“Red Green WHITE) -> “Red Green White”
(“w3resource”) -> “W3resource”
(“dow jones industrial average”) -> “Dow Jones Industrial Average”

Sample Solution-1:

Python Code:

``````def test(strs):
return ' '.join(word.capitalize() for word in strs.split())
text ="Red Green WHITE"
print("Original string:", text)
print("Capitalize the first letter and lowercases the rest:")
print(test(text))
text = "w3resource"
print("\nOriginal string:", text)
print("Capitalize the first letter and lowercases the rest:")
print(test(text))
text = "dow jones industrial average"
print("\nOriginal string:", text)
print("Capitalize the first letter and lowercases the rest:")
print(test(text))
```
```

Sample Output:

```Original string: Red Green WHITE
Capitalize the first letter and lowercases the rest:
Red Green White

Original string: w3resource
Capitalize the first letter and lowercases the rest:
W3resource

Original string: dow jones industrial average
Capitalize the first letter and lowercases the rest:
Dow Jones Industrial Average
```

Sample Solution-2:

Python Code:

``````def test(strs):
return ' '.join(i[0].upper() + i[1:].lower() for i in strs.split())
text ="Red Green WHITE"
print("Original string:", text)
print("Capitalize the first letter and lowercases the rest:")
print(test(text))
text = "w3resource"
print("\nOriginal string:", text)
print("Capitalize the first letter and lowercases the rest:")
print(test(text))
text = "dow jones industrial average"
print("\nOriginal string:", text)
print("Capitalize the first letter and lowercases the rest:")
print(test(text))
```
```

Sample Output:

```Original string: Red Green WHITE
Capitalize the first letter and lowercases the rest:
Red Green White

Original string: w3resource
Capitalize the first letter and lowercases the rest:
W3resource

Original string: dow jones industrial average
Capitalize the first letter and lowercases the rest:
Dow Jones Industrial Average
```

## Python: Tips of the Day

Inserting if statements using conditional list comprehensions:

```x = [1, 2, 3, 4, 5, 6]
result = []
for idx in range(len(x)):
if x[idx] % 2 == 0:
result.append(x[idx] * 2)
else:
result.append(x[idx])
result
```

Output:

```[1, 4, 3, 8, 5, 12]
```
`[(element * 2 if element % 2 == 0 else element) for element in x]`

Output:

```[1, 4, 3, 8, 5, 12]
```
`[element * 2 for element in x if element % 2 == 0]`

Output:

```[4, 8, 12]
```
